Answer:
Work done, W = 0
Explanation:
It is given that,
Mass of the object, m = 10 kg
Distance covered by the person, d = 100 m
Speed of the person, v = 2 m/s
We need to find the work done by this person. We know that the product of force and distance is equal to the work done by the person. Mathematically,
[tex]W=F\times d[/tex]
[tex]W=m\times a\times d[/tex]
Since, the acceleration is equal to the rate of change of velocity. Here, the person is moving the mass with a constant velocity. So, there is no change in velocity, a = 0
As a result, the work done by the person is 0 J. So, the correct option is (c). Hence, this is the required solution.
