Answer 1

Hey mate!!!

$<b >Here is your answer ;</b >$

Given,
Height, h is 3m.
Mass of the man is 60 kg.

And time taken is 2sec.

Then,
Potential energy of the man is mgh
= 60 * 3 * 10
= 1800 J.

Then,
Power is $\frac{Work} {time taken}$

Average power is $\frac{1800} {2}$

= 900 J/s

So, 900 J/s is the correct answer...
