Newton's 2nd law with an incline plane (I think....help0 The 1930 kg cable car shown in the figure descends a 200-m-high hill. In addition to its brakes, the cable car controls its speed by pulling an 1830 kg counterweight up the other side of the hill. 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? I solved for this and found that the braking force was 3320 N needed One day the brakes fail just as the cable car leaves the top on its downward journey. What is the runaway car's speed at the bottom of the hill? I have no clue how to approach this I drew out my diagrams but with every anwer I came up with I was wrong I think it was the setup If you would mind could someone just explain the setup please?
