A 100g block on a frictionless table is firmly attached to one end of a spring with k=20N/m. The other end of the spring is anchored to the wall. A 20g ball is thrown horizontally toward the block with a speed of 5.0m/s.

a.) If the collision is perfectly elastic, what is the ball's speed immediately after the collision?

b.) What is the maximum compression of the spring?

c.) Repart parts a and b for the case of a perfectly inelastic collision.
