1. The problem statement, all variables and given/known data Determine the magnitude of the horizontal force Fp required to push a block of a mass 30 kg, up along an inclined plane, with a constant acceleration of 0.8m/s2. The plane makes an angle of 25° to the horizontal and the coefficient of kinetic friction between the plane and the block is 0.21. (Hint: The solution involves setting up simultaneous equations in terms of x and y components of the unknown force, i.e. Fpcos25° and Fpsin25°, and then solving them for Fp.) 2. Relevant equations I asked my teacher how to do it but i didn't really understand him. He gave me this formula to find Fp. The answer given by the book is 250 N. Fpcosθ = Fg +μ(mgcosθ + Fpsinθ) + Fa where Fp= Force applied/of pull Fa= Acceleration Force Fg= Force due to gravity/weight 3. The attempt at a solution I have plugged in the given but i still get the wrong answer (400+ N). Can someone please explain this to me? Help me please. Please.
