Question

Body has the ratio of their mases 1:4 having same kinetic energy find the ratio of their momentum

Answer 1

hey mate

here is your answer

let the kinetic energy of the both body be k(each).

let their masses be m and 4m

therefore,the momentum of first body=√(2*m*k)

the momentum of second body=√(2*4m*k)

thus,their ratio=√(2*m*k)/√(2*4m*k)

=√1:√4

=1:2(answer)
