A block of mass M is pulled along a horizontal surface by applying a force at angle `theta` with the horizontal. The friction coefficient between the block and the surface is `mu`. If the block travels at a uniform velocity, find the work done by this applied force during a displacement d of the block.

A

`(mu mgd)/((cos theta+mu sin theta))`
