A 130 g block on a frictionless table is firmly attached to one end of a spring with k=26 N/m. The other end of the spring is anchored to the wall. a 26 g ball is thrown horizontally toward the block with a speed of 5.6 m/s. if the collision is perfectly elastic, what is the ball's speed immediately after the collision? what is the maximum compression of the spring?
