A 5.0-kg box has an acceleration of 2.0m/s2 when it is pulled by a horizontal force across a surface with K=0.50 . Find the work done over a distance of 10 cm by (a) the horizontal force, (b) the frictional force, and (c) the net force. (d) What is the change in kinetic energy of the box?
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.
