Solve this:

27. A body is moving up an inclined plane of angle  θ  with an initial kinetic energy E. The coefficient of friction between the plane and body is  μ . The work done against friction before the body comes to rest is .
1   μ cos θ E   cos θ + sin θ                                     2   2 μ E   C o s   θ 3   μ E   c os   θ μ   cos   θ - sin   θ                                   4   μ E   c os   θ μ   cos   θ + sin   θ
