Solution and Explanation
No, the person has not done any work in the physics sense.
Justification:
In physics, work is done only when a force causes a displacement of an object in the direction of the force. Here, the bundle of hay does not move while he is holding it, so displacement = 0. Therefore, work done = 0, even though the person feels tired.

- Soni says that the acceleration in an object could be zero even when several forces are acting on it. Do you agree with her? Why?
- In each of the following a force, F is acting on an object of mass, m. The direction of displacement is from west to east shown by the longer arrow. Observe the diagrams carefully and state whether the work done by the force is negative, positive or zero.
