A man seeking to set a world record wants to tow a 104,000-kg airplane along a runway by pulling horizontally on a cable attached to the airplane. The mass of the man is 93 kg, and the coefficient of static friction between his shoes and the runway is 0.78. What is the greatest acceleration the man can give the airplane? Assume that the airplane is on wheels that turn without any frictional resistance.
Max force the man can apply is
F= F(fr)= μN=μmg=0.78•93•9.8=710.9 N
a=F/M = 710.9/104000=0.0068 m/s²
