Answer:The impulse delivered to the ball is .

Explanation:By

Impulse Theorem, the motion of the tennis ball is modelled after the following expression:(1)Where:

– Mass of the ball, in kilograms.

– Vector of the initial velocity, in meters per second.

– Vector of the final velocity, in meters per second.

– Impulse, in meters per second.

If we know that , and , then the impulse delivered to the ball is:

The impulse delivered to the ball is .
