A stubborn, 120 {\rm 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 {\rm N}. The coefficients of friction between the mule and the ground are \mu _{\rm s} = 0.80 and \mu _{\rm k} = 0.50. Is the farmer able to move the mule?

What is your thinking on this?

forcefriction=mu*mg

pulling force-forcefriction=mass*accleration

I don't really know!
