A stubborn 146 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 604 N. The coefficients of friction between the mule and the ground are 0.800 for static friction and 0.500 for kinetic friction. Calculate the additional force (in N) that the farmer will need from his son in order to move the mule assuming that the local acceleration due to gravity is 9.80 m/s2.
