A 12-kg box slides down a 30° frictionless ramp at constant speed as shown in the animation (position is in meters and time is in seconds). Note that both gravity and the hand do work on the box.
What is the work done on the box by the external force (hand) and the total work done on the box
during the animation? Start
-60 J / 0 J.
