A small box with a mass 32.0 g is released from rest at point A, which is at the top edge of a large, hemispherical bowl. Assume that the size of the box is small as compared to the radius of the bowl so that the box can be treated as a particle. The work done by friction on the box when it moves from point A to point B at the bottom of the bowl has magnitude 0.640 J. Between points A and B, how much work is done on the rock by the normal force?1. Between points A and B, how much work is done on the rock by gravity?2. What is the speed of the rock as it reaches point B?3. Of the three forces acting on the rock as it slides down the bowl, which (if any) are constant and which are not? Explain.4. Just as the rock reaches point B, what is the normal force on it due to the bottom of the bowl?
