Answer:
Work done, W = 0 J
Explanation:
It is given that,
Mass of the bag, m = 7 kg
If a person carries a bag of groceries 1.2 m above the ground at constant speed across a 2.7 m room. We need to find the amount of work done on the bag he the process. It is given by :
Where
θ = angle between the force and the direction of motion. Here, θ = 90° (its weight is acting vertically downward and it is moving forward)
Since, cos(90) = 0
⇒ Work done, W = 0 J
So, the work done on the bag is zero. Hence, the correct option is (b) "0 J".
