The block continues in the same direction with a constant speed....
A small block with mass m is attached to a cord passing through a hole in a frictionless, horizontal surface. The block is initially revolving at a distance r from the hole with a speed vr. as shown. (a) By what force F, applied by the hand is the block held rotating? The cord is then pulled additionally from below, shortening the radius of the circle in which the block revolves to At this new distance, (b) what will the...
