A stubborn 130 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. part a calculate the force which farmer needs to apply to budge the pig.

<span>Unless the pig moves static friction acts on it once the pig starts moving kinetic friction comes in to play so when the pig is not moving=frictional force acting on it =normal force*co-efficient of static friction.</span>
