Answer:
(A) Impulse will be 1.116 kgm/sec
(B) Force will be equal to 1116 N
Explanation:
We have given mass of the basketball m = 0.120 kg
Initial speed of the ball 
Final speed of the ball 
(A) Impulse delivered by the ball is equal to the change in momentum
So impulse will be equal to 
So impulse will be 1.116 kgm/sec
(B) Time is given for which force is exerted 
We know that impulse is equal to 

F = 1116 N
Answer:
