The figure shows a 2000 kg cable car descending a high hill. A counterweight of mass
1800 kg on the other side of the hill provides a force that helps to slow down the car.

applies its breaks. The result is that the car descends at constant speed. Assume that
there is no friction between the slope and the car or counterweight. How much braking
force does the cable car need to descend at constant speed? a) 3800 N b) 2900 N c)
2000 N d) 980 N e) 0 N - Answers -A. 3800N
