What is 75 mph in kph?

mph stands for miles per hour. So to convert to kph (kilometers per hour), one has to recall that 1 mile is approximately 1.600 km, and then 75 mph = 75x1.600 = 120.0 kph.

How fast is 40 mph in kph?

40 mph is equivalent to 64.37 kilometers per hour.

If 100J of energy are required to draw a bow what is the kinetic energy of the arrow at the moment of release?

At the moment of release, all the energy stored in the bow (100J) is converted to the kinetic energy of the arrow. So, the kinetic energy of the arrow at that moment is 100J.

How fast is 12mph in kph?

If you look on most speedometers (not all I'm sure) there is a second number above or below the main numbers on the speedo dial. The second set of numbers is the KPH. At about 62 MPH (if I remember right) is 100 KPH. So to answer your question I figure that 110 KPH is approximately 68 MPH, give or take.

How do you convert angular rotation into force?

You create a purely 'rotatory force' or torque when you have two forces of equal magnitude but opposite direction pushing or pulling on an object. The greater the forces the greater the torque, and the greater the perpendicular distances between the two forces the greater the torque.

Note that because the forces are equal and opposite, the object will not accelerate in any direction. But because there is a perpendicular distance between the forces the object will start to rotate.

Does a propelled object continue increasing in speed infinitely in a vacuum?

For a start, it is not possible to propel it indefinitely. Where should the energy come from?

On the other hand, there is a speed limit in the Universe, called the "speed of light". An object can approach the speed of light, but never quite reach it, much lass pass that speed.

Is the sum of all the energy of the molecules of an object is called the temperature of that object?

its called internal energy..

temperature (defined as the degree of measure of heat, which is a form of energy) just helps you to compare the energies of two or more systems...

How do you find the final velocity without the initial velocity?

You use the information that you do have, along with the formulas, equations, and

definitions you've learned that express the relationship among quantities such as

position, speed, velocity, acceleration, and time, to find the unknown quantity.

Is running an kinetic or potential energy?

The potential energy of the mass of the sky diver is transformed into kinetic energy during the free fall. The kinetic energy of the free fall is transformed into kinetic energy and heat of the air when the parachute is deployed.

What is the difference between forward kinemaics and reverse kinematics in robotics?

Forward kinematics calculates the end-effector position of a robot based on the joint angles. Reverse kinematics, on the other hand, determines the joint angles required to position the end-effector at a desired location. Essentially, forward kinematics looks at the robot from joint angles to end-effector position, while reverse kinematics works from end-effector position back to joint angles.

How many miles is 26 knots?

One knot is equal to one nautical mile per hour. Therefore, 26 knots is equal to 26 nautical miles.

How could kinetic energy damage?

Think of an 8KG sledgehammer. Its head is moving at a high velocity, and it hits you in the head.

If you follow this example to its logical conclusion (in theory only, you may struggle to follow anything if you try this as an experiment), You will see some of the ways kinetic energy can cause damage to many things.

What is the formula for traveling feet per second?

To calculate traveling feet per second, you would typically divide the distance traveled in feet by the time taken in seconds. The formula is:

Feet per Second = Distance (in feet) / Time (in seconds)

Is determined by mass and velocity of an object?

Momentum and kinetic energy are determined by the mass and velocity of an object.

Momentum = m• v, where m is mass in kg and v is velocity in m/s.

KE = 1/2mv2, where m is mass in kg and v is velocity in m/s.

What will be the kinetic energy of the ram of a pile driver when it suddenly undergoes a 10-kJ decrease in potential energy?

10-kj will be added to the Kinetic Energy. Remember the law of conservation of energy. E=PE+KE. and Efinal = Einitial.

How fast is 100-120kph in miles per hour?

100-120 kph is equivalent to approximately 62-75 mph.

Can you get a ticket for going 60 mph in a 75 mph in AZ?

Yes, in Arizona, exceeding the posted speed limit can result in a ticket regardless of how fast you are going compared to the limit. It is important to always follow the posted speed limits to avoid any potential fines or penalties.

What is 104 mph in kmh?

167.371776 Km/h

Ill tell you a cool trick go to google.com and type

"104 mph to kph" and it will tell you so you can use it again.

Would you be consuming more fuel when driving at 120 kph 130 kph or stopping and starting?

You would consume more fuel when driving at 130 kph compared to 120 kph due to increased air resistance. Stopping and starting frequently in city driving consumes the most fuel due to acceleration from a standstill.

What factor are involved in determining the kinetic energy of a amoving object?

The kinetic energy of a moving object is determined by its mass and velocity. The formula for kinetic energy is KE = 0.5 * mass * velocity^2, where KE is kinetic energy, mass is the object's mass, and velocity is its speed.

What is 1500 km per hour in miles per minute?

To convert 1500 km per hour to miles per minute, first convert kilometers to miles by multiplying by 0.6214. 1500 km/hr * 0.6214 = 932.1 miles per hour. Next, divide miles per hour by 60 to get miles per minute: 932.1 miles/hr / 60 min ≈ 15.5 miles per minute.

What is 500 yards per hour in meters per minute?

500 yards per hour is approximately equivalent to 228.6 meters per hour. To convert this to meters per minute, you would divide by 60 (as there are 60 minutes in an hour), resulting in approximately 3.81 meters per minute.
