Science Buddies: "Ask an Expert"

1. The airplane is moving with a force of 800N. However, there is a wind force of 40N and air friction of 75N pushing against the airplane. What is the overall net force?
2. 4 people are playing a tug of war. Two are pulling on the right side. Two are pulling on the left side. On the right side, one is pulling with a force of 60N and the other with a force of 70N. On the left side, one is pulling with a force of 30N. How much force should the second person on the left apply to keep the rope on equilibrium?
Please help me! Thank you!
