Figure P1.48 shows an object whose mass is 5 lbm attached to a rope wound around a pulley. The radius of the pulley is 3 in. If the mass is lowered at a constant velocity of 5 ft/s, determine the power transmitted to the pulley, in horsepower, and the rotational speed of the pulley, in revolutions per minute (rpm). The acceleration of gravity is g = 32.2 ft/s2
