29. A 100kg cart starts from rest on a 20m high incline. At the bottom of the incline, the speed of the cart is 16 m/s. Neglect air resistance and consider the free fall acceleration g = 9.8 m/s². L = 60 m h = 20 m v = 15 m/s Figure (Q.29) (a) Draw the free body diagram of the cart when it is moving along the incline. (b) How much work has been done by the friction force? (c) What is the average friction force acting on the cart? [3 marks] [4 marks]
