Question

A peron holds a bundle of hay for 30 minutes and gets tired. Has he done work or not

​

Answer 1

Answer:

Yes.

Explanation:

if he is holding hay he is still using his energy to hold and so he is working.

Answer 2

No. The work done will be zero. This is because work done = Force × Displacement.

In this case, there is no displacement from mean position.

Even though energy is being consumed by him, from the context of Physics, work done shall be zero.
