117600 = m (kg) * 9.8 m/s^2 * 200 mm = 60 kg.
yes ====================== While your leg is swinging but before it hits the ball, your leg has kinetic energy. When your toe contacts the ball, it transfers kinetic energy to the ball, after which the ball also has some kinetic energy. (Your leg does not lose all of its kinetic energy, because it's still moving even after the ball takes off.)
What is the question?
A 0.650 kg basketball is dropped out of a window that is 6.46 m above the ground. The ball is caught by a person whose hands are 1.32 m above the ground. How much work is done on the ball by its weight?
For a given amount of energy 4 kg ball would move faster compared to 6 kg ball
Four and half
GPE = m*g*h = 294 Joules.

On earth: Potential energy = mgh so: 2kg * 9,81m/s^2 * 5m = 98,1 Joule
117600 = m (kg) * 9.8 m/s^2 * 200 mm = 60 kg.
The answer will depend on their positions (heights).
GPE = mgh = 4 x 9.8 x 3 = 117.6J

GPE = mgh (mass x gravity x height). You can use 9.8 for gravity.
GPE=mgh hat : 15.68J trophy: 29.4J globe: 22.0J Therefore, the trophy has the greatest GPE.
