His kinetic energy is 5,688 kilogram-meters.
Now you do the calculation, and if you arrive at the same solution,
then you'll know that your work is correct.

Where is the maximum and minimum kinetic and potential energy found as a ball drops?
A ball at rest contains only potential energy. A ball in motion contains almost all kinetic energy. But it gets tricky here. A free falling ball that has not yet reached terminal velocity has no potential energy. That energy is being given up to kinetic energy. Once the ball reaches terminal velocity in Earth's atmosphere, air resistance holds back further conversion of potential energy to kinetic.
What kind of energy is in a falling object?
Kinetic energy of a falling object can be calculated for a specific height at a specific point since a falling body accelerates which means that it's velocity is changing every moment. To calculate the kinetic energy of a falling body at a certain height, we should know the mass of the body and its velocity at that point.Then we can apply the following formula: K.E. of an object = 1/2(mv2)
Does potentail energy have an influence on the final velocity of a falling object?
yes it does. u can calculate the final velocity of the falling object with the following eqn: initial potential energy= final kinetic energy or mgh = 1/2mv2 where m=mass, h = height,v=final velocity
What happends to kinetic energy when the velocity increases?
Kinetic energy is proportional to the square of the magnitude of velocity.
What will happen to the kinetic energy for an object if its mass is double but the velocity remains at the same?
Kinetic Energy = (1/2)*(mass)*(velocity)2 If you double the mass, then the kinetic energy will double If you double the velocity, the kinetic energy will increase by a factor of 4

What happens when kinetic energy is absorbed as an object moves toward the earth?
The kinetic energy increases as the velocity increases (KE = 1/2mv2) until terminal velocity is reached, at which point the velocity becomes constant, and kinetic energy will no longer increase. The potential energy and kinetic energy will be at equilibrium, where PE = -KE.
How do you find the kinetic energy of a falling nickel?
1) measure its mass and velocity. 2) Measure where its falling from. (the kinetic energy will equal the potential energy up to the instant the nickel stops).

How does velocity have an effect on kinetic energy?
The summation of potential and kinetic energy of an object is constant. When the potential energy of an object decreases the kinetic energy increases. Assume a falling stone from some high point above ground. At the beginning, the potential energy is maximum while the kinetic energy is minimum or zero. While the stone is falling, the kinetic energy increases while the potential energy increases (with the summation of both is constant). When the stone reaches the ground, the kinetic energy is maximum and the potential energy is zero.
Why can an object have kinetic energy and potential energy?
Because they are not mutually exclusive. Take for example a falling object; while falling at a given velocity it has (.5)(mass)(velocity)2=Kinetic Energy but also has the potential energy of whatever distance it has yet to fall, which equals (mass)(gravity)(height)=Potential Energy These two types of energy equal the Total Energy of the falling object, which never changes as it falls.

When you have kinetic energy you must have?
When you have kinetic energy, you must have a mass and a velocity since kinetic energy is half the product of the mass and the square of the velocity.
What happends to kinetic energy when the velocity increases?
Kinetic energy is proportional to the square of the magnitude of velocity.
Is velocity kinetic energy?
No. This is because velocity is not a mechanical energy.
What happens to an objects kinetic energy as its velocity increases?
Kinetic Energy increases as velocity increases. Kinetic Energy = 1/2 * Mass * Velocity2
What are some objects that have kinetic energy?
Kinetic energy is the energy an object has due to its mass and its velocity. Kinetic energy is calculated with the equation: Ek = ½ mv² Since kinetic energy is proportional to mass and velocity, any object moving very slowly has a small amount of kinetic energy. Also, any very small object normally has a small amount of kinetic energy. For example, a soccer ball rolling down a hill might have a relatively small amount of kinetic energy.
