So I made 2 equations with 2 unknowns, the acceleration of the man/plane and the equal reaction pulling force between them. The normal force on the man is equal to his weight plus the vertical component of the pulling force. So we have the static friction force with respect to the pulling force...

i drew a free body diagram for the plan. Fcos9=ma i don't know the acceleration and i don't know the force by which the man is pulling :S static friction, so I can slove for maximun acceleration of the man? but if we;re talking about a cable, that means that there is also a tension force...

Homework Statement an 85 kg man plans to tow a 109000 kg airplane along a runway by pulling on a cable attached to it at an angle 9 above the horizontal. the coefficient of static friction between his between his shoes and the runway is 0.77. what is the greatest acceleration that the man...
