An 85-kg man plans to tow a 109 000-kg airplane along a runway by pulling horizontally on a cable attached to it. suppose that he instead attempts the feat by pulling the cable at an angle of 9.08 above the horizontal. 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?

The greatest acceleration the man can give the airplane is 0.0059 m/s².

Explanation:

Given that,

Mass of man = 85 kg

Mass of airplane = 109000 kg

Distance = 9.08

Coefficient of static friction = 0.77

We need to calculate the greatest friction force

Using formula of friction

Where, m = mass of man

g = acceleration due to gravity

Put the value into the formula

We need to calculate the acceleration

Using formula of newton's second law

Put the value into the formula

Hence, The greatest acceleration the man can give the airplane is 0.0059 m/s².
