Question

A mover is moving a big box out of the moving truck. She places the box on the ramp at 30 degrees to the horizontal so that she can move it out of the truck. A frictional force of 64N exists between the box and the ramp. Find the box's acceleration as it goes down the ramp.

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

$A 35 mathrm{kg}$ box rests on the back of a truck. The coefficient of static friction between the box and the truck bed is 0.300 a. When the truck accelerates forward, what happens to the box? b. Find the maximum acceleration the truck can have before the box slides backward.
