Homework Statement
I have a block on an inclined plane (the angle is 40). The block is projected with an initial speed of 2m/s and μ=0.05. I need to find the time it takes the block to go up the inclined plane and return to the point it started out.
Homework Equations
The Attempt at a Solution
I know that the force of friction will be μmgcosθ. Usually, the force bringing the block down the plane is mgsinθ.
I figure that I will need to find the acceleration and then use the equations of motion to find t, since the final speed at the top of the plane will be 0. I am having trouble setting up my equations.
Would it be that:
ma = -mgsinθ+ μmgcosθ
