3.00 kg 8m / s

2. A 15.0-kg block is attached to a very light horizontal spring of force constant 500N / m and is resting on a frictionless horizontal table. Suddenly it is struck by a 3.00-kg stone traveling horizontally at 8.00 m / s to the right, whereupon the stone rebounds at 2.00 m/s horizontally to the left. Find the maximum distance that the block will compress the spring after the collision.
