Answer:
Work done, W = 39.2 J
Explanation:
It is given that,
Mass of the block, m = 2 kg
The block is lifted vertically 2 m by the man i.e the distance covered by the block is, h = 2 m. The man is doing work against the gravity. It is given by :
[tex]W=mgh[/tex]
Where
g is acceleration due to gravity
[tex]W=2\ kg\times 9.8\ m/s^2\times 2\ m[/tex]
W = 39.2 J
So, the work done by the man is 39.2 J. Hence, this is the required solution.
