The figure below shows a 4800 kg cable car descending a high hill. A counterweight of mass 4400 kg on the other side of the hill aids the breaks in controlling the cable car’s speed. The rolling friction of both the cable car and the counterweight are negligible. a. How much braking force does the cable car need to descend with an acceleration of 0.15 m/s? b. What is the tension in the cable connecting the two cars in part a? Counterweight 200 m
