Question #4bc3e

Answer 1

see below

Explanation:

Remember,

`"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 (`"F"_g`) is in the downward direction while the displacement (`"d"`) is in the upward direction.
