A hockey puck of mass 0.11 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: u(x) = 0.1 + 0.05x. (a) Find the work (in J) done by the kinetic frictional force on the hockey puck when it has moved from x = 0 to x = 3 m. J (b) Find the work (in J) done by the kinetic frictional force on the hockey puck when it has moved from x = 3 m to x = 5 m. J
