A stubborn 110 kg pig sits down and refuses to move. To drag the pig to the barn, the exasperated farmer ties a rope around the pig and pulls with his maximum force of 800 N. The coefficients of friction between the pig and the ground are μs=0.80 and μk=0.50.

Calculate the force which farmer needs to apply to budge the pig.

force=mg*mu=110* 9.8*.8
