A hockey 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 μ(x)=0.1+0.05x. Find the work done by the kinetic frictional force on the hockey puck when it has moved from x=0 to x=2 m.
