Answer
The impulse on the ball is $~~(8.25~kg~m/s)~\hat{j}$
Work Step by Step
In part (a), we found that the change in the ball's momentum is $~~(8.25~kg~m/s)~\hat{j}$
The impulse on the ball is equal to the change in the ball's momentum.
Therefore, the impulse on the ball is $~~(8.25~kg~m/s)~\hat{j}$.
