The situation is shown below :

                                   

The horizontal components of velocity are to be considered for imparting impulse as vertical components are in the same direction thus impulse in the vertical direction is zero.

The impulse is given by a change in momentum.

                Initial momentum   =     -mv \cos \Theta

               Final momentum    =         mv \cos \Theta

Thus impulse is         =\ mv \cos \Theta\ -\ (-\ mv \cos \Theta)\ =\ 2mv \cos \Theta

or                              =\ 2\times0.15 \times15\ \cos 22.5 ^{\circ}

or                              =\ 4.16\ Kg\ m/s
