A brake test for an automobile is conducted. During the brake test, the automobile of mass 1800 kg (including driver) is travelling at the speed of 110 km/hr as it passes point A, and the car descends a hill of 1 in 2 (Sine). The driver applies brakes so as to bring the car speed at B to 50 km/hr. The total frictional resistance to motion is 235 N. Using Work-Energy Method, Calculate the following required to bring the car to 50 km/hr from 110 km/hr in 210 m (From Point A to Point B) B Determine the Value of Total Energy about Point A TEa= Determine the Value of Total Energy about Point B TEb= Determine the Value of Breaking Force needed Fb= N A
