Answer 2

Explanation:

Given A man is lower in a bucket full of water with an acceleration of 1 metre per second square the work done by him is a positive work

• Given So a man is lowering a bucket full of water with an acceleration of 1 m/s^2
• Work is either positive or negative. So if the force done is in the same direction to the displacement of the object then the force done will be positive.
• Also if the force done is in the opposite direction to the displacement, the force done will be negative.
• Now the force and displacement are in the same direction and hence work done will be positive.
