Answer:
My arms are doing a negative work
Step-by-step explanation:
When you set something on the ground, the displacement of the object set towards the ground is in the downward direction. which means that, in this case, there is a downward displacement.
As the object is set on the ground, the force exerted by the arms on the object acts in the upward direction.
Summarily, direction of force is upwards while the direction of displacement is downwards.
Since the force and displacement act in opposite direction, a negative work is said to be done.
