3 kg crate is pulled by a 181 N force (parallel to the incline) up a rough incline. Assume that the incline makes an angle of 31.

A 13.3 kg crate is pulled by a 181 N force (parallel to the incline) up a rough incline. Assume that the incline makes an angle of 31.8° with the horizontal and that the coefficient of kinetic friction is 0.436. The crate has an initial speed of 1.60 m/s. It is pulled a distance of 5.90 m. What is the change in mechanical energy of the crate? Answer in units of J and use 9.8 m/s2 for g.
