A cable car is pulled up a mountain at a speed of 4m/s by a cable with a tension of 1000 N. The journey takes 5 mins. What is the work done in getting the car to the top?
Answered by DrBob222
Work = mgh and Tension = mg so work = T*h.
h = rate*time = 4 m/s x 5 min x (60 sec/min) = ?
You knoq T and h. Solve for work.
