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. /3C] b) You can push the box with a force of 200 N parallel to the ramp, but the box does not move. Determine: 6K] i) the components of the weight parallel to and normal to the direction of the ramp. ii) the frictional force. c) Create a formula relating the frictional force, the weight of the box, the force applied and the angle of inclination of the ramp, given the net force parallel to the ramp is zero. [/3A] 6 d) The mover fastens a rope to the box, and pulls, applying a force of 200 N at an angle of 15° to the ramp. The box still does not move. Determine the new frictional force. [ /3KI e) Adjust your formula from question 2, to include the angle between the ramp and the applied pulling force, given the net force parallel to the ramp is zero. [__________/3T] f) Create a formula relating the normal force, the weight of the box and the force applied, given the net force perpendicular to the ramp is zero. 1 of 3 [/3A]

[ /3T] f) Create a formula relating the normal force, the weight of the box and the force applied, given the net force perpendicular to the ramp is zero. L /3A] g) The mover applies a pulling force of 180 N at an angle of 45° and the box slowly begins to move. Determine the frictional force and the normal force acting on the box. [_________/3K] 7 h) Explain why the mover was able to move the box on his third attempt. Refer to the forces involved. I. /3C] i) Describe what the mover should try in order to get the box inside the van. L /3C] j) The mover gets another box and sets it on the ramp. He pulls it at an angle of 30° to the ramp, but it does not move. If the frictional force is 80 N and the normal force is 50 N, determine the weight of the box and the magnitude of the pulling force.
