J (b) Relative to the configuration with the stone at the top edge of the well, what is the gravitational potential energy of the stone-Earth system when it reaches the bottom of the well? J (c) What is the change in gravitational potential energy of the system from release to reaching the bottom of the well? J

You drop a 2.40 kg book to a friend who stands on the ground at distance D = 13.0 m below. If your friend's outstretched hands are at distance d = 1.70 m above the ground (see the figure), (a) how much work Wg does the gravitational force do on the book as it drops to her hands? (b) What is the change ΔU in the gravitational potential energy of the book-Earth system during the drop? If the gravitational potential energy U of that system is taken to be zero at ground level, what is U (c) when the book is released and (d) when it reaches her hands? Now take U to be 100 J at ground level and again find (e) Wg, (f) ΔU, (g)U at the release point, and (h) U at her hands.

In the figure, a small block of mass m = 0.015 kg can slide along the frictionless loop-the-loop, with loop radius R = 17 cm. The block is released from rest at point P, at height h = 7R above the bottom of the loop. How much work does the gravitational force do on the block as the block travels from point P to (a) point Q and (b) the top of the loop? If the gravitational potential energy of the block-Earth system is taken to be zero at the bottom of the loop, what is that potential energy when the block is (c) at point P, (d) at point Q, and (e) at the top of the loop? (a) Number Units (b) Number Units (c) Number Units (d) Number Units (e) Number Units
