Q. A 110 g block on a frictionless table is firmly attached to one end of a spring with k = 28 N/m. The other end of the spring is anchored to the wall. A 28 g ball is thrown horizontally toward the block with a speed of 5.8 m/s. What is the highest compression of the spring for a perfectly elastic impact? If the impact is perfectly inelastic, what is the ball's speed immediately after the impact? What is the highest compression of the spring for a perfectly inelastic impact?
