Problem 3

You drop a 2.00 kg book to a friend who stands on the ground at distance D ! 10.0 m below. If your friends outstretched hands are at distance d ! 1.50 m above the ground (Fig. 8-30), (a) how much work Wg does the gravitational force do on the book as it drops to her hands? (b) What is the change "U in the gravitational potential energy of the bookEarth 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) "U, (g) U at the release point, and (h) U at her hands. d D Figure 8-30 3 and 10
