(a) The impulse delivered to the ball by the racket is 5.24 kg.m/s
(b) The work that the racket does on the ball is -35.1 Joule
<h3>Further Explanation</h3>
<u>Given :</u>
mass of ball = m = 0.06 kg
initial velocity = v₁ = -50.4 m/s
final velocity = v₂ = 37.0 m/s
<u>Unknown :</u>
(a) Impulse = I = ?
(b) Work = W = ?
<u>Solution :</u>
<h2>Question (a) :</h2>
In this question , we could use the formula from Second Law of Newton :
