A tug-of-war match happens between Team Blue and Team Red. Each of Team Blue’s members has an average mass of 76 kg and exerts an average force of 1225 N horizontally. Each of Team Red’s members has an average mass of 78 kg and exerts an average force of 1275 N horizontally. What is the tension in the section of rope between the teams?
Vector F₁ = 625 N makes an angle of 2700 when rotated counterclockwise from the +x axis. Vector F2 = 875 N makes a 1200 angle from Vector F₁ when rotated
counterclockwise. What is the magnitude a vector needed to balance the two forces?
