A block of mass m is initially at rest on a rough incline of

A block of mass m is initially at rest on a rough incline of incline angle and attached to an initially relaxed nonlinear spring which exerts a restoring force of magnitude fres x kx ax Here is measured parallel to the incline from the block s initial position where the spring is relaxed The coefficient of kinetic friction is itself position dependent and is given by Hk x M Ho 1 x L e the the incline gets smoother as the block descends Leave g symbolically Find the block s speed as a function of a assuming that it does start moving down the incline and for the first phase of motion during which it is moving down the incline given that it starts from rest at x 0
