After drawing the graph, I still dun know how to solve the problem. I know I should use F=ma, but I really dun know about tension. btw, am I drawing the right sketch? thanks so much!Two identical street cars are connected by a cable. One car has fallen off a bridge. The other car is going up a slope of 14 degrees, and has on its breaks, mu=0.13. People rush to jump on the second car so it will be heavy enough to pull up the first car. What is the initial acceleration of the cars, in ft/s^2
