I'm stuck on this question. It's form the Edexcel m1 textbook, exercise 3i question 6. It reads:

A particle of mass 0.5kg is pushed up a line of greatest slope of a rough plane by a horizontal force of magnitude P N. The plane is incline to the horizontal at angle a where tan a=0.75 and the coefficient of friction between P and the plane is 0.5. The particle moves with constant speed.
Find
a) the magnitude of the normal reaction between the particle and the plane
b) the value of P

Any help would be greatly appreciated. Thanks

First things first, you draw a diagram. Work out your angles and then resolve both ways like you'd do with any other question. What part are you stuck on and how much have you worked out?
