A small block on a frictionless horizontal surface has a mass of 0.0225 kg . It is attached to a massless cord passing through a hole in the surface. (See the figure below (Figure 1).) The block is originally revolving at a distance of 0.285 m from the hole with an angular speed of 1.65 rad/s . The cord is then pulled from below, shortening the radius of the circle in which the block revolves to 0.165 m . You may treat the block as a particle
