One day while cleaning up brush, I get my cousin's tractor, which weighs 1450 N, stuck in amud pit. After my cousin stops laughing at me, the two of us and another cousin attach ropes tothe tractor and pull on it with the forces at the angles shown in the diagram below132788 N985 N31°53411 NUsing the coordinate system shown at right,(a) calculate the resultant force on the tractor,(b) the angle at which the resultant force acts, and(c) the acceleration of the tractor.+X+y

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 barge is pulled by the two tugboats shown in the following figure. One tugboat pulls on the barge with a force of magnitude 4000 units of force at 15 above the line AB (see the figure and the other tugboat pulls on the barge with a force of magnitude 5000 units of force at 12 below the line AB. Resolve the pulling forces to their scalar components and find the components of the resultant force pulling on the barge. What is the magnitude of the resultant pull? What is its direction relative to the line AB?

A warehouse worker pushes a crate along the floor, as shown in the figure (Figure 1), by a force of 19 NN that points downward at an angle of 45 degrees below the horizontal. Find the horizontal component of the push. Your answer should be positive if the force is to the right, negative if the force is to the left. Express your answer in newtons. Find the vertical component of the push. Your answer should be positive if the force is upward, negative if the force is downward. Express your answer in newtons.
All the ffollowing require vector diagrams: 1. Two horses are used to pull a carriage. They act at 30⁰ to each other. One horse pulls with a 550 N force and the resultant force is 1000 N. With what force is the second horse pulling the carriage? 2. A 1000 N crate rests on a 20⁰ incline. Resolve the force of the crate into components that are parallel and perpendicular to the incline. State the magnitudes of the components. 3. A swimmer is swimming at 1 knot (nautical miles per hour) on a heading of N30⁰W. The current is flowing at 2 knots towards a bearing of N10⁰E. Find the velocity of the swimmer, relative to the shore. 4. A ski chairlift is suspended between two towers that are 60 m apart. When the chairlift is 20 m from one tower, the cable sags 1 m. The chairlift is loaded with four skiers with a combined weight of 250 N (including the mass of the chair). What are the tensions in the two parts of the cable?
In rock climbing, various rope and pulley systems have been devised to help haul up heavy loads, including injured climbers. A rescuer is hauling up an injured climber who weighs 570 NN using the rope and pulley system shown in (Figure 1). (The ropes in this figure are drawn at various angles for clarity, but you can assume they're all vertical.) What is the tension in rope 1, the rope that the rescuer pulls on? What is the tension in rope 2?
