Question: A 2-kg block is released 4 m from a massless spring with a force constant k = 100 N/m that is fixed along a frictionless

A 2-kg block is released 4 m from a massless spring with a force constant k = 100 N/m that is fixed along a frictionless plane inclined at 30°, as shown in Figure.

(a) Find the maximum compression of the spring.

(b) If the plane is rough rather than frictionless, and the coefficient of kinetic friction between the plane and the block is 0.2, find the maximum compression.
