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 1) 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. 2) 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. 3) 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.
