Q3 of 42 Page 29

A cricket ball of mass 150 g has an initial velocity u = (3î + 4ĵ) m s-1 and a final velocity V = -(3î + 4ĵ) m s-1 after being hit. The change in momentum (final momentum-initial momentum) is (in kg m s1)

We know that change in momentum =final momentum – initial momentum 0r now we have given mass 150g i.e. m1=m2=m=0.15kg also and so





So


Therefore, option (c) is correct.
