A machine pulls a 42 kg trunk 2.4 m up a 37o ramp at constant velocity, with the machine's force on the trunk directed parallel to the ramp. The coefficient of kinetic friction between the trunk and the ramp is 0.35. What are (a) the work done on the trunk by the machine's force and (b) the increase in thermal energy of the trunk and the ramp?
