A stubborn 120 kg mule sits down and refuses to move. To drag the mule to the barn, the exasperated farmer ties a rope around the mule and pulls with his maximum force of 800 N. The coefficients of friction between the mule and the ground are mu,s = 0.8 and mu,k = 0.5. Is the farmer able to move the mule?

The attempt at a solution

friction=μs(normal force)

friction=0.8(120kg)

friction=120(9.8)(.8)

frictionS=940.8

940.8N>800N

The farmer will not be able to get the mule to move.

Does this look correct?
