Acrate of mass 9.6 kg is pulled up a rough incline with an initial speed of 1.40 m/s. the pulling force is 102 n parallel to the incline, which makes an angle of 19.9° with the horizontal. the coefficient of kinetic friction is 0.400, and the crate is pulled 5.04 m. (a) how much work is done by the gravitational force on the crate? j (b) determine the increase in internal energy of the crate–incline system owing to friction. j (c) how much work is done by the 102-n force on the crate? j (d) what is the change in kinetic energy of the crate? j (e) what is the speed of the crate after being pulled 5.04 m? m/s
