How kinetic energy does a 4.0 kg ball sitting 2.0 meters off the ground have?
The ball has potential energy due to its position above the ground. To calculate its kinetic energy, we need more information such as its velocity or the forces acting on it.
A bob of mass of 0.18 kilograms is released from a height of 45 meters above the ground level. What is the value of the kinetic energy gained by the bob at the ground level?
The kinetic energy gained by the bob at ground level can be calculated using the principle of conservation of energy. The potential energy at the initial height is converted into kinetic energy at ground level. Thus, the kinetic energy gained by the bob at ground level is equal to the initial potential energy, which is calculated as mgh, where m is the mass of the bob (0.18 kg), g is the acceleration due to gravity (9.8 m/s^2), and h is the height (45 meters). Substituting these values, we find the kinetic energy gained to be 79.38 Joules.

How do you calculate in kinetic energy just before it hits the ground with a 200 kilogram and is raised 10 meters above the ground?
You can calculate the kinetic energy just before hitting the ground using the formula for potential energy and kinetic energy. First, calculate the potential energy at the initial height using mgh (mass x gravity x height). Then equate this value to the kinetic energy just before hitting the ground using the formula 1/2mv^2 (0.5 x mass x velocity squared) and solve for the velocity.
What if An apple with a mass of 0.95 kilograms hangs from a tree branch 3.0 meters above the ground. If it falls to the ground what is the kinetic energy of the apple just as it reaches the ground?
The potential energy of the apple while hanging is given by mgh, where m=0.95 kg, g=9.8 m/s^2, and h=3 m. At the moment it reaches the ground, all this potential energy will have converted to kinetic energy, thus the kinetic energy would be equal to the initial potential energy. Calculating mgh gives a potential energy of 27.93 J, which would be the kinetic energy just before hitting the ground.

A cat with a mass of 4.50 kilograms sits on a ledge 0.800 meters above the ground If it jumps to the ground how much kinetic energy will it have just as it reaches the ground?
If a cat that has a mass of 4.50 kilograms sits on a ledge that is 0.800 meters above ground and it jumps down to the ground, it will have a specific amount of kinetic energy just as it reaches the ground. In this instance, the answer would be 35.3J.

If you have a 2kg pendulum bob that is 6 meters above the ground at its high point and 1 meter at its low point how can you figure the kinetic energy?
Calculate the potential energy at its highest point. Don't use the 6 meters above the ground - use the 5 meter difference from the lowest point. This part of the potential energy gets converted into kinetic energy, when the pendulum is at its lowest point. Just assume that all the potential energy (for the 5 meters difference) get converted into kinetic energy.Calculate the potential energy at its highest point.

Why 12.0 kg rock slides off the edge of a bridge and falls into the water 25.0 meters below. What is the kinetic energy of the rock just as it hits the water?
The gravitational potential energy of the rock at the edge of the bridge is converted to kinetic energy as it falls. Use the formula for gravitational potential energy (mgh) to find the potential energy at the top, then equate that energy to the kinetic energy (1/2 * m * v^2) just before impact to solve for the final velocity. Finally, use this velocity in the kinetic energy formula to calculate the kinetic energy just as it hits the water.
A 5kg object is being lifted to a height of 8 meters and is dropped what is the kinetic energy of the object at 2 m?
After falling 6 meters, potential energy corresponding to those 6 meters will be converted to kinetic energy. The potential energy (for the 6 meters) is mgh = (5 kg)(9.82 m/s2)(6 m) = 294.6 J, so that is also the kinetic energy, since potential energy has been converted to kinetic energy.After falling 6 meters, potential energy corresponding to those 6 meters will be converted to kinetic energy.
