Part C and D please

A 4.5 kg box slides down a 4.5-m -high frictionless hill, starting from rest, across a 1.8-m -wide
horizontal surface, then hits a horizontal spring with spring constant 550 N/m . The other end of
the spring is anchored against a wall. The ground under the spring is frictionless, but the 1.8-m-
long horizontal surface is rough. The coefficient of kinetic friction of the box on this surface is 0.24.
vi = 9.4
