11. Point A is on the ground, and points B and C are h = 20 m above the ground. Point B is directly above point A, and point C is L = 60 m away from point A as shown. a) How much work must be done by an external agent to move a 3 kg object from rest at point A to rest at point B? B b) How much work must be done to move the same object from rest at point A to rest at point C? 11. Point A is on the ground, and points B and C are h = 20 m above the ground.
