You are moving into a new place, and you rented a U-Haul

You are moving into a new place, and you rented a U-Haul cargo van to transport your home furniture and different boxes. Moving the boxes from the house to the van is done through a dolly you are using. However, the dolly has broken during a move. There are still several boxes which must now be carried manually from the home to the van. The ramp leading into the mover's van is at a 30° angle to the ground. You are carrying a box weighing 200 N from the house. You are placing the box on the ramp, planning to push it the rest of the way into the van. a) Given the diagram below, use arrows to indicate the directions of the frictional force, the gravitational force and the normal force (perpendicular to the incline) of a box sitting on a ramp. b) You can push the box with a force of 200 N parallel to the ramp, but the box does not move. Determine: i) the components of the weight parallel to and normal to the direction of the ramp. ii) the frictional force.
