A small block with a mass of 0.0600 kg is attached to a cord passing through a hole in a frictionless, horizontal surface. The block is originally revolving at a distance of 0.45 m from the hole with a speed of 0.73 m/s. The cord is then pulled from below, shortening the radius of the circle in which the block revolves to 0.15 m. At this new distance, the speed of the block is 2.19 m/s.

(a) what are the magnitude and direction of the velocity of the red glider after the collision? magnitude 3.33 m/s correct: your answer is correct. direction correct: your answer is correct. (b) is this collision elastic?
