Impulse I = change in momentum

              I= mv’-mv

we will take vertival and horizontal component

angle theta = 45’

              I= (mvcos45=mvsin450)-(mvcos45-mvsin45)

 vertical resolution cancelout & horizontal adds up             

              I=2mvsin45

              I=2*0.02*15*1\root2

               = 0.6*1\root2

               = 0.424328 N-s
