Combining Conservation Law A 15.0kg block is attached to a very light horizontal spring of force constant 500.0N/m and is resting on a frictionless horizontal table. Suddenly it is truck by 3.00kg stone traveling horizontally at 8.0m/s to the right, whereupon the stone rebounds at 2.00m/s horizontally to the left. Find the maximum distance that the block will compress the spring after collision.
