A body (material point) weighing 2 kg freely falls from a height equal to 6 m relative to the Earth’s surface.
a) What is the potential energy of a body at a distance of 3 m from the Earth’s surface?
b) Find the kinetic energy of the body at the surface of the Earth.
a) Ep = mgh = 2 * 10 * 3 = 60 J
b) Ek = En1 = mgH = 2 * 10 * 6 = 120 J
