Question

4. The back of a pick-up truck is 1.2 m above the ground. As an aid to unloading, a 5.8 m long ramp is set up against it so that boxes from the back of the truck could slide down it. The coefficient of kinetic friction between one of the boxes and the ramp is 0.42, causing the box to stop sliding down the ramp in 2.0 seconds, as measured by a physics student using her phone as a stop-watch. a. Make a diagram illustrating this situation and a free-body diagram showing all of the forces acting on the box
