Three students watch a jet plane roar by over their heads at a constant velocity. Student A says that the force of the jet engines must be the same as the force of air resistance on the plane. Student B says that the force of the jet engines has to be larger than the force of air resistance because the plane is moving forward. Student C says that the plane must have turned off its jet engines for a moment because it is moving at a constant velocity.
Using a Claim, Evidence, Reasoning argument, determine which student is correct.

Please write a 3 page essay describing how this class has changed your life for the better. Be sure it is positive, because it could be important.
Just kidding. Three sentences will do. Paragraphs would really impress me, though.
