Question

A 0.2000-kg block on a frictionless (? = 0) table is attached to one end of a spring with Hooke's constant k = 30.0 N/m. The other end of the spring is firmly attached to a wall. A 0.0250-kg ball is thrown horizontally toward the block at 2.00 m/s. In the case of a perfectly elastic collision, what will be the speed of the ball immediately after the collision? 1.56 m/s

What will be the maximum compression of the spring due to the collision? I got 0.036m but it's incorrect

In the case of a perfectly inelastic collision, what would be the speed of the ball immediately after the collision? I got 0.22m/s but it's incorrect

And the maximum compression of the spring? I got 0.02m but it's incorrect.
