Answer 2

The power of done by the man is 435.56 Watts.

Explanation:

It is given that,

Mass of the weightlifter, m = 200 kg

It is height to a height of 2 meter in 9 seconds.

We need to find the power done by the man. Power of a source is given by work done per unit time. It is given by :

$P=\dfrac{W}{t}$

W is work done, W = mgh

$P=\dfrac{mgh}{t}$

$P=\dfrac{200\times 9.8\times 2}{9}$

P = 435.56 Watts

So, the power of done by the man is 435.56 Watts. Hence, this is the required solution.
