Four sled dogs are pulling a 1000 kg load. Sled dog A is pulling the load at 20 N, 10 north of east. Sled dog Bis pulling the load at 55 N, 70° north of east. Sled dog C is pulling the load at 45 N, 33° north of west, while sled dog D exerts 30 N at a direction of 80 south of west. What is the resultant force acting on the load?

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 force F1 of magnitude 6.00 units acts on an object at the origin in a direction = 30.0 above the positive x axis (Fig. P3.7). A second force F2 of magnitude 5.00 units acts on the object in the direction of the positive y axis. Find graphically the magnitude and direction of the resultant force F1+F2. Figure P3.7

A force F1, of magnitude 6.00 units acts on an object at the origin in a direction = 30.0 above the positive x-axis (Fig. P3.8). A second force F2 of magnitude 5.00 units acts on the object in the direction of the positive y-axis. Find graphically the magnitude and direction of the resultant force F1 + F2?. Figure P3.8
Three concurrent forces are pulling the box, the first one pulls 5 N, North; second pulls 5N, South and and the third one pulls 8 N, East. What is the magnitude and direction of their resultant force? a. 18 N, East b. 8 N, West c. 8 N, East d. 3N, West
Three people pull simultaneously on a stubborn donkey. Jack pulls eastward with a force of 94.5 N,94.5 N, Jill pulls with 88.1 N88.1 N in the northeast direction, and Jane pulls to the southeast with 181 N.181 N. (Since the donkey is involved with such uncoordinated people, who can blame it for being stubborn?) Find the magnitude of the net force the people exert on the donkey. What is the direction of the net force? Express this as the angle from the east direction between 0°0° and 90°,90°, with a positive sign for north of east and a negative sign for south of east.
Two locomotives on opposite banks of a canal pull a vessel moving parallel to the banks by means of two horizontal ropes. The tensions in these ropes are 2000 N and 2400 N while the angle between them is 600. Find the resultant pull on the vessel and the angle between each of the ropes and the sides of the canal.
In a two-dimensional tug-of-war, Alex, Betty, and Charles pull horizontally on an automobile tire at the angles shown in the picture. The tire remains stationary in spite of the three pulls. Alex pulls with force FA→ of magnitude 212 N, and Charles pulls with force FC→ of magnitude 177 N. Note that the direction of FC→ is not given. What is the magnitude of Betty's force FB→ if Charles pulls in the direction drawn in the picture?
The helicopter view in above figure shows two people pulling on a stubborn mule. The person on the right pulls with a force F1of magnitude 120N and direction of θ 1=60.0 0 The person on the left pulls with a force F2of magnitude 80.0N and direction of θ 2=75.0 0 . Find (a) the single force that is equivalent to the two forces shown and (b) the force that a third person would have to exert on the mule to make the resultant force equal to zero. The forces are measured in units of newtons (symbolized N).
