An arrangement of two pulleys, as shown in the figure, is used to lift a 48.0-kg mass
Question:
(a) What is the mechanical advantage of this system? (In other words, by what factor is the force you exert to lift the weight multiplied by the pulley system?)
(b) What is the change in the potential energy of the weight when it is lifted a distance of 4.00 m?
(c) How much work must be done to lift the 48.0-kg mass a distance of 4.00 m?
(d) What length of rope must be pulled by the person lifting the weight 4.00 m higher in the air?
