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?
Vector F1 = 625 N makes an angle of 270 degrees when rotated counterclockwise from the +x axis. Vector F2 = 875 N makes a 120 degree angle from Vector F1 when rotated counterclockwise. What is the direction of the vector needed to balance the two forces?

the following example is given: vector1 =+(60.0N)i+(103.9N)j vector2 =+(75.2N)i−(27.4N)j vector 3=−(100.0N)i+(0.0N)j vecor net =+(35.2N)i+(76.5N)j Convert this net force to polar coordinates; that is, find the total vector magnitude and angle. If three forces, 1 , 2 , and 3 , are in equilibrium, what is the relationship between the sum of the first two forces and the third force? Write your answer as an equation. onsider the vector = −(51.7 N)i + (63.9 N)j (a) Convert this value to polar coordinates (magnitude and angle). (b) When converting this to polar coordinates, what answer does your calculator give you for the angle of the vector? Explain whether this is correct or not (including the correct angle if applicable).
