Question

Derive an expression for the work Wf done on the block by friction as it travels from the top of the incline to the bottom. (Express your answer in terms of the variables μ, m, g, h, and α)

When α is decreased, does the magnitude of Wf increase or decrease?

A block of massm is released from rest at the top of
an incline that makes an angle a with the horizontal.
The coefficient of kinetic friction between the block
and incline is uk. The top of the incline is a vertical
distance h above the bottom of the incline.
