  4. sir i think it might be an aliter but i am not getting answer we can write equation-1 as mod(vc)=v{v^2+20^2} also by using formula velocity of centre of mass we get equation-2 as vector(vc)=(80/14)i+(10v/14)j so again equation-3 from 2 mod(vc)=v{(80/14)^2+(10v/14)^2} so equating 1&3 we can get answer but its not coming.......... please help
