Knight P6.24 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 a maximum force of 800 N. The coefficients of friction between the mule and the ground are g = 0.8 and k = 0.5. Is the farmer able to move the mule? Draw a free body diagram as part of your solution.
