M2 question - Power watch

1. A car of mass 1200 kg is being driven up a straight road inclined at 5 degrees to the horizontal. Resistive forces acting on the car total 1960 N.

a) Draw a diagram showing all the forces acting on the car.
b) The car is moving with constant speed 15ms^-1.
i. Show that the tractive force produced by the engine is 2985 N.
ii.Determine the rate at which the engine is doing work.
c) The engine has a meaximum power output of 60kW. Assuming resistive forces are constant, find the maximum possible speed of the car up the same slop, it its initially at rest.

Well i solved all the other parts except part b) ii...

what i did was dat i used the formula Power = F x v

2. 2985x15 + 0.5mv2 ?
Maybe. I'm not entirely sure but I think you add work done + energy.
3. I triedd ...but the answer is tooo big thanks for the help though
