A body of mass m is thrown up at a velocity u along a plane of inclination theta. If coefficient of friction between the body and the plane is mu, what would be the work done by friction when the body rises up to the highestpoint of itsmotion?

1.	A body of mass m is thrown up at a velocity u along a plane of inclination theta. If coefficient of friction between the body and the plane is mu, what would be the work done by friction when the body rises up to the highestpoint of itsmotion?
Answer» ANSWER :`(u^2mum)/(2(mu+tan THETA))`
