250 kg concrete wheel with a radius of 1.50 m is being pulled up a hill by a 725 kg cow, with a rope attached to the wheel and the cow. There is a 35.5 cm tall rock protruding out of the hill. Calculate the tension in the rope when the wheel is just starting to lift off of the hill to go over the protruding rock? What's the minimum coefficient of static friction between the cow and the hill for the cow to be able to pull the wheel over the rock?
