While catching a cricket ball of mass `200g` moving with a velocity of `20ms^(-1)`, the player draws his hands backwards through `20cm`. Find the work done in catching the ball and the average force exerted by the ball on the hand.

Explanation

To solve the problem, we will follow these steps:

### Step 1: Convert the mass of the ball from grams to kilograms
The mass of the cricket ball is given as 200 grams. To convert this to kilograms, we divide by 1000.

\[ m = \frac{200 \text{ g}}{1000} = 0.2 \text{ kg} \]
