Exercise 7.9 A small rock with mass 0 16 kg is released from rest at point A, which is at the top edge of a large, hemispherical bowl with radius R=0.42 m (Eigure 1) Assume that the size of the rock is small compared to R, so that the rock can be treated as a particle, and assume that the rock slides rather than rolls. The work done by friction on the rock when it moves from point A to point B at the bottom of the bowl has magnitude 0 22 J Figure A 11°C Bakth B R U A < 1 of 1 O Ara > ▼ Y Between points A and B. how much work is done on the rock by the normal force?
