A cable car is pulled up a slope by a constant force of 5000 newtons at a uniform speed of 6 metres per second. It takes the car 4 minutes to complete the journey.
(i) How much work is done in getting the car to the top of the slope?
(ii) How much work would be done if the speed were 12 metres per second (the force remainging the same)?
