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: µ (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
