#### Explanation:

Remember,

$\text{Work"="Force"xx"Displacement}$

While catching the ball, the direction of the force exerted by the fielder is opposite to the displacement of the ball, just like the truck here.

Here, the gravity (${\text{F}}_{g}$) is in the downward direction while the displacement ($\text{d}$) is in the upward direction.
