Answer:

$J=P_2-_{}P_1=0$

Step-by-step explanation: To redirect the ball, or reverse its direction, the Impulse required would be:

$\Delta P=0\rightarrow\text{ For the Ball}$

Because the initial and final velocity should remain the same:

$\begin{gathered} \text{ The Impulse required would be:} \\ \Delta P=P_2-_{}P_1 \\ P_2=_{}P_1\Rightarrow P=(1.9\operatorname{kg})\cdot(21ms^(-1))=39.9\cdot(kg\cdot m\cdot s^(-1)) \\ \therefore\Rightarrow \\ \Delta P=0 \end{gathered}$
