1. Homework Statement [/b]
A block of weight mg sits on an inclined plane as shown. A force of magnitude F is applied to pull the block up the incline at constant speed. The coefficient of kinetic friction between the plane and the block is Mu.
What is the total work done on the block by the applied force as the block moves a distance up the incline?
Express your answer in terms of any or all of the variables Mu, m, g, theta, L and F
W=FDcos(theta)
It seems like since W=FDcos(theta) the answer would simply be FLcos(theta) but its telling me that is wrong, can anyone give me an idea of what I'm missing. Thanks!
