Point A is on the ground, and points B and C are h = 20 meters above the ground. Point B
is directly above point A, and point C is L =
45 meters away from point A as shown.
How much work must be done by an external
agent to move a 5 kg object from rest at point A to
rest at point B?
(b) How much work must be done to move the same
object from rest at point A to rest at point C?
