A ladder of weight W stands on a rough floor and rests against a frictionless wall, illustrated above. It is only stable if the angle between the ladder and the ground is greater than theta (theta > 60 degree). a. Find the coefficient of static friction between the floor and the ladder. b. A child of weight 4W places the ladder against the wall at angle 70 degree(theta = 70 degree). Calculate how far up the ladder it is safe for the child to climb.
