How to resolve power of an object on inclined planes?
A car of mass 2000 kg travels up a slope of 30.0° at a uniform speed of 15.0 m s-1.If the frictional resistance is 10% of the weight of the car, at what power is the engine working?

1 Answer
Explanation:
Since the speed "v" is given is given, apply
From Newton's second law
Force explanation:
Note that car is traveling uphill at constant speed, hence the net force must be zero. There are 3 forces acting on the car, the force (F) of the engine pushing the car uphill, the gravitational pull modified by the slope (
