Kinematics

Steel is used for modern roller coaster frames because it is stronger, more durable, and allows for more complex designs compared to wood. Steel construction also provides smoother rides, requires less maintenance, and offers greater structural integrity for higher speeds and taller heights.

150 knots is approximately equal to 278 kilometers per hour.

Recoil is the backward force exerted on a gun when a bullet is fired. This force is a result of Newton's Third Law of Motion, which states that for every action, there is an equal and opposite reaction. Recoil can affect accuracy and may cause discomfort or injury to the shooter if not properly managed.

1km/hr=0.911344ft/sec

So,

1km/hr-----------0.911344ft/sec

75km/hr----------x

x=75*0.911344

x=68.3508ft/sec

Therefore,

75km/hr=68.3508ft/sec(68.3 approximately)

When objects are bound gravitationally in centrifugal motion, the objects are said to be in orbit of each other.

The total force you would get by adding a 6N force with a 4N force is 10N. This is because forces can be added together like numbers in mathematics to get the total force applied.

A radio is an example of electrical potential energy because it relies on stored electrical energy to function. When the radio is turned on, this potential energy is converted into kinetic energy in the form of sound waves.

The product of velocity and time gives displacement, which represents the distance and direction an object has moved over a specific time period. Displacement is a vector quantity, meaning it has both magnitude and direction.

8000 mph is approximately Mach 10.5 under standard conditions.

You can't, since the slope of the graph means average velocity and the area of the graph has no meaning. The only way to find instantaneous velocity from position-time gragh is by plugging the data into the kinematic equations to get the answer.

Edit: Actually you can if you take the derivative of the equation of the curve it will give you the equation of the velocity curve

As a basketball rises toward the basket, its kinetic energy decreases. This is because its velocity decreases as it moves against the force of gravity. At the highest point of its trajectory, the basketball's kinetic energy is lowest.

As the temperature of a gas sample increases, the kinetic energy of the gas particles also increases. This is because temperature is a measure of the average kinetic energy of the particles in the sample. Therefore, an increase in temperature corresponds to an increase in the average kinetic energy of the gas particles in the sample.

v=d/t

Algebra can be used to isolate for the t value:

Multiply by t: vt=d

Then, divide by v: t=d/v

Now, simply plug in the given values for the variables, and solve.

1 kilometer per hour is approximately equal to .6214 miles per hour.

Consequently, 209 kph is approximately 129.8726 mph.

The slope of a distance versus time graph represents the speed or velocity of an object. A steeper slope indicates a higher speed, while a gentler slope indicates a slower speed. If the slope is negative, it means the object is moving in the opposite direction.

To convert from dollars per hour to dollars per minute, divide the hourly rate by 60 (since there are 60 minutes in an hour). So, if 90 dollars are earned per hour, this would be equivalent to earning 1.5 dollars per minute (90 / 60 = 1.5).

Yes, according to Newton's Third Law of Motion, when two bodies collide, they apply equal and opposite forces on each other. This means that the force one body exerts on the other is equal in magnitude but opposite in direction to the force the other body exerts back.

256,000 kilometers per hour is approximately 159,072 miles per hour.

This is easier to understand when the graph is horizontal.

Speed is defined as distance / time. Rearranging the equation: distance = speed x time. In the graph, that would be proportional to the area of the rectangle under the (horizontal) speed line.

If speed is variable, the graph can be approximated by many small rectangles. The same reasoning as above applies to each one. This method - of separating an area into many small parts - is called "integration".

When the speed of an object is doubled, its kinetic energy increases by a factor of four. This is because kinetic energy is proportional to the square of the velocity. Therefore, doubling the speed results in four times the kinetic energy.

1.8km = 1 nautical mile or knot

20 knots is equivalent to approximately 10.29 meters per second.

To convert 900 feet per day to yards per hour, we first need to find the equivalent value in yards for 900 feet. Since 1 yard is equal to 3 feet, 900 feet is equal to 300 yards. Next, we convert the rate from days to hours by considering there are 24 hours in a day. Therefore, 300 yards per day is equivalent to 12.5 yards per hour.

As an object gains kinetic energy (movement), its potential energy decreases. This is because the energy is being converted from potential energy to kinetic energy. The total mechanical energy of the object (kinetic energy + potential energy) remains constant if no external forces are acting on the object.

450 knots is approximately equal to 518.34 miles per hour.
