QUESTION 5 A mаn pushes а 10kg crаte upwards against a rоugh slоpe that makes an angle оf 20° with the horizontal. The impact force is 100N parallel to the surface of the slope. The crate is pushed 5m upwards with an initial speed of 1.5m.s–1. The coefficient of friction between the crate and the surface is 0.4. 5.1 Draw a labeled free force diagram to show all the forces acting on the crate. (4) 5.2 Calculate the work done by gravity. (3) 5.3 Calculate the energy transferred due to friction. (6) 5.4 Work done by the man to push the crate upwards. (1) 5.5 State the work-energy theorem in words. (2) 5.6 Use the principle of work and energy and calculate the magnitude of the final velocity of the crate after it has been pushed up the slope 5m. (4) [20]
