Hello !

Since momentum, P = m×v,
where P is momentum,
m is mass of an object, and
v is velocity of an object.
So mass of first object is given i.e.,ma,
therefore, P = ma×v ....... 1 equation,

Now mass of second object is mb,
therefore, P = mb×v .......2 equation,

Now when we divide 1 equation by 2 equation,
we get,
Ratio = a/b


Hope this will be helpful to you, if u like it then plz mark it as brainliest.

have equal kinetic energy hence,

\dfrac{1}{2}m_A (v_A)^2 = \dfrac{1}{2}m_B (v_B)^2
