Answer:
The acceleration of man is .
Explanation:
The tension on the block is given as,
(1)
Where,
T=tension
m=mass of the block
g=acceleration due to gravity
a=acceleration of the block
Since the velocity is constant the acceleration i.e.a will be zero. Equation (1) can be expressed as follows:
(2)
And the tension supplied by the rope to the man is calculated as,
(3)
a'=acceleration of the man
By equalizing equations (2) and (3) we get;
The acceleration of man is i.e.none of the options is correct.
