A 15 kg black is attached to a very light horizontal spring of force constant 425.0 N/m and is resting on a frictionless table. Suddenly it is struck by a 3.00kg stone traveling horizontally at 8.00m/s to the right, whereupon the tone rebounds at 2.00m/s horizontally to the left. (a)Find the maximum distance that the black will compress the spring after the collision. (b) assume the collision is elastic.
I figured out how to do (a) and got .37m but I have no idea how to do (b), or even what its asking. If you at least know an equation I'm supposed to use that would help a ton!!
