Physics Question dealing with inclined planes?

Question

Calculate the applied force on a car with a mass of 5500 kg as it is pushed up a 25 degree incline at a constant speed. Assume friction is negligible.

Answer 1

F = mg sin a, where a is the angle of the incline.

Answer 2

Any constant pusing force greater than

(5500)*sin (25) = 2324.4 N  will keep the car moving at a constant speed. I hope this helps.
