As shown in the diagram, a 4800-kg cable car is descending a high hill. A counterweight of
mass 4600 kg on the other side of the hill aids the brakes in controlling the cable car's speed.
The rolling friction of both the cable car and the counterweight are negligible. How much
braking force does the cable car need to descend at constant speed?
