A 1200Kg car is coasting down a 30 degree hill as shown. At a time when the car's speed is 12m/s, the driver applies the brakes. a) What constant force F (parallel to the road) must result if the car A 1200Kg car is coasting down a 30 degree hill as shown. At a time when the car's speed is 12m/s, the driver applies the brakes. a) What constant force F (parallel to the road) must result if the car is to stop after traveling 100 meter. b) what is the kinetic energy of the car before braking? c) What is de potential energy the car gains because the road is going downwards. (during 100 m) d) what is the constant breaking force F
