initial velocit is v = 6i + 8 j m/svelocity of the particle will remain same in x directio therefore change in momentum in x directio is zero
initial velocity in y direction is 8 m/sfinal velocity in y direction is -8 m/schange in velocity =8-(-8 )= 16 m/schange in momentum = mass×change in velocity = 16 m
