The question says that a block is projected up a rough inclined plane, at an angle x to the horizontal. v^2=2gLSinx, L is the distance the block would travel up the slope if there were no friction (that bit can be obtained from the law of conservation of energy). On the rough plane, it travels up a distance q. By…

The question says that a block is projected up a rough inclined plane, at an angle x to the horizontal. v^2=2gLSinx, L is the distance the block would travel up the slope if there were no friction (that bit can be obtained from the law of conservation of energy). On the rough plane, it travels up a distance q. By considering the work done against friction, find an equation for the coefficient of friction.

How do I do this? I don't know how to take energy into account and deal with friction. Thanks
