As long as the mass is the same in both cases, it doesnt enter the calculations.
The height (s) from which to drop it so its velocity at impact is 100 kph (27.78 metres per second):
Use >
s = (v2 - u2) / (2 * a)
s = 771.73 / 19.64
s = 39.29 metres
>
u = 0 (initial velocity - metres per second)
v = 27.78 (final velocity - metres per second)
a = 9.82 (acceleration due to gravity - (m/s)/s)
s = ? (distance - in this case , height)

What is the kinetic energy of an object weighing 65 kg dropped from a height of 40m?
Kinetic energy is dependent on which point you are talking about. When it is about to be dropped, kinetic energy is zero. When it reaches almost hits the ground, there is maximum kinetic energy.
What is an example of kinetic energy as it applies to a vehicle?
Kinetic energy is extra energy resultant of motion. So, a moving vehicle has kinetic energy.
Two examples of potential energy converted to kinetic energy?
A pendulum hanging still at its highest point (potential energy) is released, converting its potential energy to kinetic energy as it swings back and forth. An object held above the ground (potential energy) is dropped, converting its potential energy to kinetic energy as it accelerates towards the ground.
How does a yo yo transfer potential energy to kinetic energy and back again as it moves up and down its string?
As the yo-yo falls downward, potential energy is converted to kinetic energy due to gravity. When the yo-yo reaches its lowest point and starts moving up the string, the kinetic energy is converted back to potential energy from the tension in the string. This continuous transfer between potential and kinetic energy allows the yo-yo to oscillate up and down.
What happens to a basketball's kinetic energy as it rises toward the basket?
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.
A bullet traveling upwards has what type of energy?
it has both potential and kinetic energies as when it is going upwards, the potential energy increases while the kinetic energy decreases until it reaches the top, and then the kinetic energy is zero and the potential energy is maximum.
What energy does a marble have when it is dropped?
Kinetic energy is moving energy
What energy is in a traveling bullet?
A traveling bullet primarily carries kinetic energy due to its motion through the air. This kinetic energy is derived from the initial potential energy stored in the bullet when it was fired.
What is the kinetic energy of an object weighing 65 kg dropped from a height of 40m?
Kinetic energy is dependent on which point you are talking about. When it is about to be dropped, kinetic energy is zero. When it reaches almost hits the ground, there is maximum kinetic energy.
Which has more kinetic energy a ball dropped from a height of 2m or a same ball dropped at 4m which has more kinetic energy just before it hits the ground?
The ball dropped from 4m height has more kinetic energy just before it hits the ground because it has a higher velocity due to falling from a greater height. Kinetic energy is directly proportional to both mass and the square of velocity, so the ball dropped from 4m height will have more kinetic energy than the one dropped from 2m height.
What happens to the energy of a ball that is being dropped from the height?
As the ball is dropped, its potential energy is converted into kinetic energy. The potential energy decreases as the ball falls due to gravity, while the kinetic energy increases. At the moment of impact, the kinetic energy is maximum, and the potential energy is minimum.
As a dropped penny falls toward the ground energy is converted to energy?
As a dropped penny falls toward the ground, potential energy is converted into kinetic energy. The higher the penny is dropped from, the more potential energy it has, which is converted into kinetic energy as it accelerates downwards due to gravity.
If two bicycles have the same mass but one is traveling at 10 ms and the other is traveling at 15 ms which has more kinetic energy?
The bicycle traveling at 15 m/s has more kinetic energy because kinetic energy is proportional to the square of the velocity. Since the mass is the same for both bicycles, the one traveling faster will have a greater kinetic energy.
Which car has the most kinetic energy?
A car traveling at a higher speed will have more kinetic energy than a car moving at a slower speed. So, the car with the most kinetic energy would be the one traveling at the highest speed.
What type of energy a car is traveling 45 mph have?
A car traveling at 45 mph has kinetic energy, which is the energy of motion. As the car moves, its speed and mass contribute to its kinetic energy. This energy is what enables the car to perform work and overcome resistance while in motion.
What is the kinetic energy of a ball when it is dropped from a height and it falls on a table?
it is the difference of the potential energy when the body is on the table and from the position where it is dropped.
Does kinetic energy decrease when traveling up hill?
Yes, kinetic energy decreases when traveling uphill because some of the energy is converted into potential energy to overcome gravity. This results in a decrease in the speed of the object.
