An 85 kg man tries to pull himself up the face of a boulder using a rope hooked to a tree above it. The face of the boulder created a 50.0° angle with the horizontal. If the coefficient of friction between his shoes and the boulder is 0.350, will he make it up if he pulls with 550. N of force? Remember his shoes will try to slip backwards when considering friction.
