8. A 5.00 kg box is placed at the top of a ramp that is made by propping up a 3.00 m long board to make an angle of 22.0° with the horizontal. The edge of the board makes a smooth transition to the horizontal floor. Assume friction is negligible. a) What is the magnitude of the acceleration of the box while it is on the ramp? b) What is the magnitude of normal force on the box while on the ramp? c) How long will it take the box to reach the end of the ramp?
