Q. A 13.30 kg crate is pulled by an 181N force (parallel to the incline) up a rough incline. Assume that the incline makes an angle of 31.80° 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? React in units of J and use 9.80 m/s2 for g.
