Homework Answers
Only unbalanced forces cause acceleration. Since Bill is not accelerating, the 200N force must be exactly balanced by both. Thus the the tension of the string is 200N.

Three people are playing tug of war but they are not moving. Person 1 is pulling with 100 pounds of force from a 35 degree angle relative to the X-axis in the positive difection, person 2 is pulling with 200 pounds of force relative at a 22 degree angle to the Y-axis in the negative direction for both X and Y. How much force is the 3rd person pulling with (in Newtons), and in what direction to create this scenario?

Two people play tug of war. The 100-kg person on the left pulls with 1,140 N, and the 70-kg person on the right pulls with 835 N. Assume that neither person releases their grip on the rope with either hand at any time, assume that the rope is always taut, and assume that the rope does not stretch. What is the magnitude of the tension in the rope in Newtons?

Two teams of nine members each engage in a tug of war. The first team's members have average masses of 66 kg and exert average forces of 1350 N horizontally. The second team's members have average masses of 71 kg and exert average forces of 1374 N horizontally. (a) What is the acceleration of the two teams? _ m/s2 (in the direction the heavy team is pulling) (b) What is the tension in the section of rope between the teams?...

1. In a tug-of-war game, 12 children pull on two sides of a rope. Define right as +x and left as –x. On the right, there are two children each pulling with a force of 122 N, one pulling with a force of 86 N, and three each pulling with a force of 102 N. On the left, there is one child pulling with a force of 180 N, two each pulling with a force of 90 N, and three...
