• Sir which object will fall faster
1. Heavy Object
2. Light Object

• Both the objects will fall at the same time or we can say no one will fall faster than the other because the acceleration due to gravity(9.8m/s²) is the same for every object(rather it is heavy or light), gravity will pull every object with the same amount of acceleration (gravity doesn't make any difference).
Hope u understood..
• Sir, in the question, it's not specified if the woman is pushing the barbell rod upwards, it could be that the woman is lowering the rod, so the work done should be positive.? In questions like these, how will we determine if the work done is negative or positive?
