A 60 kg trunk is pushed 5.8 m at constant speedup a 30° incline by a constant horizontal force. The coefficient of kinetic friction among the trunk and the incline is 0.17. (a) Compute the work done by the applied horizontal force. (b) Compute the work done by the weight of the trunk. (c) How much energy was dissipated with the frictional force acting on the trunk?
