Question - 2 (25Marks) (LO: 2 and 5) A brake test for an A udi O7 was conducted. During the brake test the car of masa 2810Kg (including the passengers) descends a hill of 1 in 5 (Sine) ( or =11.54 ) with a speed u =106km/h and the driver applies the brakes at point A. The frictional resiatance to the motion is 475N. Carry out the following taska: (a) Draw free body diagram showing all the forces on the car when it is moving downhill from A to B (7 Marks) (b) Using Work-Energy method or otherwise calculate average braking force required to bring the car to rest from 105km/h in 50m (trom point A to point B ).
