5. A load of 4 slugs is attached to a rope that runs over a pulley at the top of a building 100 ft. high. If a man is able to raise this load to the top of the building in 1 min, find the average power (in watt) required. 6, A 4,000 # car is at an incline that makes an angle of 15° with the horizontal. It is moving upward at constant speed 60 mph against a frictional force of 400 #. How much power (in hp) is needed to perform this task?
