1. A man seeking to set a world record wants to tow a 109,000-kg airplane along a runway by pulling horizontally on a cable attached to the airplane. The mass of the man is 85 kg, and the coefficient of static friction between his shoes and the runway is 0.77. What is the greatest acceleration the man can give the airplane? Assume that the airplane is on wheels that turn without any frictional resistance. 2. Relevant equations PLANE --> Tension=mass of plane x acceleration 3. The attempt at a solution How do I set up the equation for the net forces of man. Is force of friction - Tension = mass of man x acceleration the correct equation?
