You drop a 2.30 kg textbook to a friend who stands on the ground at distance D = 10.0 m below. Your friend's outstretched hands are at distance d = 1.50 m above the ground. How much work Wg is done on the textbook by its weight as it drops to your friend's hands if U is 100 J at the ground level. What is the change Delta U in the gravitational potential energy of the textbook-Earth system during the drop if U is 100 J at the ground level. Find U at the release point when U is 100 J at the ground level. Find U at the hands when U is 100 J at the ground level.
