George, Romeo's not often heard about older brother, was also quite in love with Juliet. One night he tried to climb a 10 m long , 25 kg ladder to her window. He put the base of the ladder 2.5 m from the wall, which was frictionless. Unfortunately for George, who was a considerable 120 kg, it had rained earlier that evening and the grass was wet. When he was but 1=4 of the way up to Juliet's window, his ladder began to slip. What was the coefficent of friction between the ladder and the grass that evening?
