M2 - Energy, Work & PowerWatch
(a) The increase in kinetic energy of the car,
(b)The decrease in gravitational potential energy of the car
(c)Neglecting any resistances to the car's motion, and assuming that the car's engine produces a constant tractive force on the car as it moves down the hill from P to Q, calculate the magnitude of the tractive force and the power of the car's engine when the car is at Q.
So I need to do this without SUVATS (It's homework) and am stuck on the last part, any help is appreciated!
work done by engine = tractive force x distance covered going down the slope.
the power will be tractive force x velocity at Q
