Suppose a block of mass M is sliding down an inclined plane which makes an angle t with the horizontal. The coefficient of kinetic friction between the plane and the block is u (assume tan(t) > u). The block is initially at rest.

a) What is the work done by friction as the block travels a distance d along the plane?

b) What is the speed of the block at this point?
