In the figure, a 0.24 kg block of cheese lies on the floor of a920 kg elevator cab that is being pulled upward by a cable throughdistance d1 = 2.1 m and then through distance d2 = 10.6 m. (a)Through d1, if the normal force on the block from the floor hasconstant magnitude FN = 2.97 N, how much work is done on the cab bythe force from the cable? (b) Through d2, if the work done on thecab by the (constant) force from the cable is 91.92 kJ, what is themagnitude of FN?
