A small block on a frictionless, horizontal surface has a mass of 0. 0250 kg. It is attached to a massless cord passing through a hole in the surface as shown in figure 4. The block is originally revolving at a distance of 0. 300 m from the hole with an angular speed of 1. 75 m/s. The cord is then pulled from below, shortening the radius of the circle in which the block revolves to 0. 150 m. Modelling the block as a particle.
