The truck, which weighs 6000 lb, is to be lowered down the slope by a rope that is wrapped around a tree. if the wheels are free to roll and the person at a can resist a pull of 100 lb, determine the minimum number of turns the rope should be wrapped around the tree to lower the truck at a constant speed. the coefficient of kinetic friction between the rope and the tree is 0.3.
