Asmall block of mass 0.91 kg slides without friction on a horizontal table. initially it moves in a circle of radius r0 = 0.63 m with a speed 1.5 m/s. it is held in its path by a string that passes through a small hole at the center of the circle. the string is then pulled down a distance of r0 - r1 = 0.12 m, leaving it at a radius of r1 = 0.51 m. it is pulled so slowly that the object continues to move in a circle of continually decreasing radius. how much work was done by the force to change the radius from 0.63 m to 0.51 m? w =
