A small block with a mass of
0.08 kg is attached to a cord
passing through a hole in a
frictionless, horizontal surface
As shown in the Figure. The
block is originally revolving
at a distance of 0.90 m from the hole with a speed of 0.60 m's. The cord is then pulled from below. shortening the radius of the circle in which the block revolves to 0.30 m. At this new distance, the speed of the block is 3.00 ms. The average force of the hand of
the man while shortening the radius of the circle is​
