How can I solve this step by
step?
(e) A car of mass 1000 kg is travelling up a 50 gradient at initial speed 10 m s-1, with the engine off. The brakes are applied at this time and the car travels distance s along the road before stopping. Friction in the brakes causes an increase in internal energy of 3 x 104 J. No energy transfer to or from the car occurs. Find distance s.
