At hokey puck of mass 0.17 kg is shot across a rough floor with the roughness different at different places, which can be described by a position-dependent coefficient of kinetic friction. For a puck moving along the x-axis, the coefficient of kinetic friction is the following function of x, where x is in m: (x)=0.1+0.05x . Find the work done by the kinetic frictional forte on the hockey puck when it h moved (a) from x=0 to x=2 m, and (b) from x=2 m to x=4 m.
