A small rock with mass m is released from rest at the inside rim of a large, hemispherical bowl (point A) that has radius R. If the normal force exerted on the rock as it slides through its lowest point (point B) is twice the weight of the rock, how much work did friction do on the rock as it moved from A to B?
