1.	A body is moving up an inclined plane of angle q with an initial kinetic energy E. The coefficient of friction between the plane and body is m. The work done against friction before the body comes to rest is
Answer» `(mu COS theta)/(E cos theta + sin theta)` `2mu E cos theta ` `(MUE cos theta)/(mu cos theta - sin theta)` `(mu E cos theta)/(mu cos theta + sin theta)` ANSWER :D
