a) how much work is done by the frictional force?

b) what is the velocity of the box when it leaves the rough surface?

c) what length of rough surface brings the box coompletely to rest?

I dont know how to do it!!

b) You are given the force of friction, what is the equation for Force? You should be able to calculate what you need to calculate the reduced velocity (you will need a SUVAT equation here also).

See if that helps at all... check back with your answers...
