A small rock with mass 0.30 kg k g is released from rest at
point A A , which is at the top edge of a large, hemispherical bowl
with radius R R = 0.48 m m (the figure (Figure 1)). Assume that the
size of the rock is small compared to R 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...
