Top Speed of a LTZ-400?

The top speed of a Suzuki LTZ-400 can vary depending on various factors such as rider weight, terrain, and modifications to the ATV. On average, a stock LTZ-400 can reach speeds of around 65-70 mph.

What is the kinetic energy of a person on a treadmill?

There is no single answer. Velocity is relative, and that means that the kinetic energy of a body also is relative. To calculate the kinetic energy you have to choose a reference frame, and the answer will be different depending on if you choose the person, the belt of the treadmill or the moon. Neither answer is more right or wrong than any other.

What is 120km in mph?

120 km is about 74.56 miles

1 mile is about 1.61 km or 0.621 mi = 1 km


1 mi = 1.609 km

120km/h x 1mi/1.609km = 75 mi/h
If you are looking for mph to kph then use the following

Mph X 1.609344 = Kph
Kph / 1.609344 = Mph

If a object travels 90 feet in 1.5 seconds how fast is it goin?

It depends on how long the object is. If the object is a dot, it will take 1.5 sec.

This is not true, the size of the object is not important. If it is a car, a fly, or a plane it is all the same!

If you take 90 mi/hr and multiple it by 5820ft you get ft/hour. This is 523800 ft/hr. Then divide this by 60 to get ft/min which is 8370, then divide it by 60 to get ft/sec., which is 145 ft/sec. Since you are only going 60 ft. divide 60/145 this is .41 sec. So it takes about a 1/2 sec. at 90 miles an hour to go 60ft.

How far away is a thunderstorm if you SEE a flash of lightning and then HEAR thunder 10 seconds later?

When lightning occurs and creates thunder you see the lightning immediately because light travels so fast (abot 186,000 miles per second). But sound travels much slower so you don't hear the thunder until several seconds after it occurs. I believe the approximate rule that is used is sound travels about 1 mile in 5 seconds. So if it is 15 seconds before you hear the thunder then the storm is about 3 miles away.

Is killing hippies bad?

Killing anyone is considered morally wrong and illegal, including hippies. It is important to resolve conflicts peacefully and respect each individual's right to life and freedom of expression. If you are experiencing difficulties with hippies or any other group, it is recommended to seek constructive ways to address the issues without resorting to violence.

Describe the change in kinetic energy when the temperature of an object increases?

The more an objects kinetic energy increases the more it's temperature increases. An object that is traveling at 30 miles per hour will have a higher temperature than an object traveling at 10 miles per hour. This is in part due to friction. Mostly however, it is due to the fact that kinetic energy excites atoms in the object raising the objects temperature. You could put it like this: temperature = energy + atoms. Hope this helps.

If a basketball player throws a ball from 2.0m in the air towards the hoop 10m away If the hoop is 3.05m off the ground and the initial angle is 40 degrees what is the initial velocity?

The initial velocity of the ball can be calculated using the kinematic equation for projectile motion. By using the vertical component of velocity (V0y) and the time of flight, we can determine the initial velocity needed for the ball to reach the hoop. The velocity components are V0x = V0 * cos(θ) and V0y = V0 * sin(θ), where θ is the initial angle. The time of flight in this case is determined by the vertical motion of the ball, and it can be found by using the equation of motion for the vertical direction, considering the initial vertical velocity, the gravitational acceleration, and the vertical displacement of the ball. Once these values are calculated, the initial velocity can be computed by combining the horizontal and vertical components of the motion.

A world class sprinter can burst out of the blocks to essentially top speed of about 11.5 ms in the first 15m of the racewhta is the average acceleration of the sprinter?

The average acceleration of the sprinter can be calculated using the formula ( a = \frac{v_f - v_i}{t} ), where ( v_f = 11.5 , \text{m/s} ), ( v_i = 0 , \text{m/s} ), and ( t = 15 , \text{m} ). Substituting these values into the formula gives an average acceleration of approximately 0.77 m/s².

How pure is speed?

Speed can be considered purely as a measure of velocity, which is the rate of change of an object's position with respect to time. In this sense, speed itself is a quantitative and objective measurement. However, the context in which speed is used, such as in sports or transportation, may involve subjective factors that can impact how we perceive speed.

What is the top speed for a stock 2002 XC SP 700?

The top speed of a stock 2002 XC SP 700 is typically around 90-95 mph, depending on factors such as rider weight, track condition, and environmental conditions.

100 mph to kph?

100 mph is equal to 160.93 kph (kilometers per hour).

Why trains do not stop immediately after applying brakes?

Trains do not stop immediately after applying brakes due to their large mass and momentum. It takes time for the brakes to slow down the moving train, and the distance needed to stop depends on the train's speed, weight, and the effectiveness of the braking system. Additionally, train brakes are designed to prevent skidding and provide a smooth and controlled stop.

Does an atom's nucleus hold a large amount of kinetic energy?

Yes, the nucleus of an atom holds a large amount of potential energy due to the strong nuclear forces binding the protons and neutrons together. This potential energy can be released as kinetic energy during nuclear reactions.

Why is electricity a form of kinetic energy?

I believe electrical energy is considered potential energy and not kinetic. Kinetic energy is when an object is moving, electrical energy is a stored energy that can be converted to kinetic energy.

How many mph do you have to go to go 870 feet in 2 minutes?

To cover 870 feet in 2 minutes, you would need to travel at an average speed of 7.25 feet per second. Converting this to miles per hour, you would need to travel at approximately 4.95 miles per hour to cover that distance in that time.

What are the kinetic moving sculptures that Alexander Calder invented?

Alexander Calder is known for inventing mobiles, which are kinetic sculptures that move in response to air currents. He also created stabiles, which are stationary sculptures that give the illusion of movement through their abstract shapes and forms. Calder's innovative use of wire and metal transformed sculpture into a dynamic and interactive art form.

Miguel biked 29040 ft in an hour convert this to mph?

29,040 feet in one hour converts to 5.5 miles per hour.

What is the definition of point of concurrency?

A point of concurrency is a point where three or more lines, segments, or rays intersect or meet. Common points of concurrency in geometry include the centroid, circumcenter, incenter, and orthocenter of a triangle.

What is rotational kinematics?

Rotational kinematics is the study of the motion of objects that spin or rotate around an axis. It involves concepts such as angular velocity, angular acceleration, and rotational analogs of linear motion equations like displacement, velocity, and acceleration. Rotational kinematics helps describe how objects move and rotate in a circular path.

A plane can travel with a speed of 80 mi-hr with respect to the air determine the resultant velocity of the plane magnitude only if it encounters a 10 mi-hr headwind?

The resultant velocity of the plane is 70 mi/hr. This is because the headwind subtracts 10 mi/hr from the plane's airspeed of 80 mi/hr, resulting in a net speed of 70 mi/hr in the direction of travel.

What will be the direction of friction on a accelerating car by the road?

The direction of friction on an accelerating car by the road is opposite to the direction of the car's motion. As the car accelerates forward, the frictional force between the tires and the road acts in the opposite direction to resist the car's motion and provide the necessary traction for it to move forward without slipping.

When can the equations of kinematics not be used?

Equations of kinematics may not be accurate when dealing with very high speeds close to the speed of light due to relativistic effects. Similarly, they may not be applicable in quantum mechanical systems that involve particles on very small scales. Additionally, for systems with significant air resistance or non-constant forces, kinematic equations may not provide accurate results.
