In a tug-of-war game on one campus, 15 students pull on a rope at both ends in an effort to displace the central knot to one side or the other. Two students pull with force 196 N each to the light, four students pull with force 98 N each to the left, five students pull with force 62 N each to the left, three students pull with force 150 N each to the right, and one student pulls with force 250 N to the left. Assuming the positive direction to the tight, express the net pull on the knot in terms of the unit vector. How big is the net pull on the knot? In what direction?
A boy sits in a tire that is attached to a rope that passes over a pulley fastened to the ceiling and then passes back down to the boy's hands. The weight of the boy plus the tire is W. What is the force with which the boy must pull on the free end of the rope to support weight in the tire?
A Jeep is stuck in the mud. The driver has a winch that can pull on its cable with a force of 45,000 N.

On her way to visit Grandmother, Red Riding Hood sat down to rest and placed her 1.20 kg basket of goodies beside her. A wolf came along, spotted the basket, and began to pull on the handle with a force of 6.40 N at an angle of 25 degree with respect to vertical. Red was not going to let go easily, so she pulled on the handle with a force of 12.2 N. If the net force on the basket is straight up, at what angle was Red Riding Hood pulling from the vertical?
A boy has filled his toy box with all his favorite toys and it trying to drag it across the floor. The toy box has a mass of 35 kg (including the toys) and the child pulls with a force of 24 N at an angle of 30 degrees above horizontal (he is pulling mostly horizontally, but some of the force is pulling up). How will the normal force between the box and the ground change when the boy starts pulling?

Problem 56. Your car is stuck in a mud hole. You are alone but have a long, strong rope. Having studied physics you tie the rope tautly to a telephone pole and pull on it sideways as in the figure below. A) Find the forces exerted by the rope on the car when 0 = 3° and you are pulling with a force of 400 N and the car does not budge. B) How strong must the rope be if it takes a force F of 600 N to move the car when 0 = 4°. Pole Car
A boy has filled his toy box with all his favorite toys and it trying to drag it across the floor. The toy box has a mass of 35 kg (including the toys) and the child pulls with a force of 24 N at an angle of 30 degrees above horizontal (he is pulling mostly horizontally, but some of the force is pulling up). How will the normal force between the box and the ground change when the boy starts pulling? Your answer: The normal force will increase when he pulls. The normal force will decrease when he pulls. The normal force will stay the same.
