The car shown below, travels an actual distance of 300m from A to B along the road surface. The velocity of the car at A is 90 km/h and the velocity of the car at B is 72 km/h. The car rolls against an average road resistance (rolling friction, wind resistance, etc) of 210 N. If the car has a mass of 1.5 t, and if B is 30 m higher than A, solve what must be the constant force P exerted by the motor USING THE WORK ENERGY METHOD.
