Situation 2: A crate of mass 10.0 kg is pulled up a rough incline with an initial speed of 1.50 m/s. The pulling force is 100N parallel to the incline, which makes an angle of 20.0° with the horizontal. The coefficient of kinetic friction is 0.400, and the crate is pulled 5.00 m. 18. Determine the increase in internal energy of the crate-incline system due to friction. 19. How much work is done by the 100-N force? 20. What is the change in kinetic energy of the crate?
