Aperson with mass m stands on a ladder of mass m that leans against a frictionless vertical wall and makes an angle of 53° measured from the horizontal. the ladder does not slip on the horizontal surface due to a static frictional force between the ladder and the ground. some of the forces exerted on the ladder can produce torques on the ladder. using the contact point between the ladder and the ground as a reference, which force(s) exerted on the ladder produce clockwise torques?
