Question

just curious if i did this right if not what was the mistake i made

4.A 2.00kg block initially at rest is released from point A, as shown. The curved portion of the track is frictionless The horizontal track, including the portion under the spring, has a kinetic coefficient of friction = 0.1. (a) What is the maximum compression of the spring? { Take k-30N/m} (b)Where does the block ultimately comes to rest? (6-points) A h=1.5m k d=10m
