A block of weight w sits on a plane inclined at an angle theta. The coefficient of kinetic friction between the plane and the block is mu.
A force F is applied to push the block up the incline at constant speed.
What is the change in potential energy of the block, DeltaU, as it moves a distance L down the incline?
answer in terms of some or all of the following: mu, w, theta, L.
What is the work W done by the applied force of magnitude F?
answer in terms of some or all of the following: mu, w, theta, L.
What is the work W_f done on the block by the frictional force?
answer in terms of some or all of the following: mu, w, theta, L.
