    If we take the example of a gun and bullet, where the gun has mass M1 and bullet has mass m2 , and we know that the bullet have a lesser mass travels at a greater final velocity and hence possesses greater kinetic energy.

    Now i am confused upon how using the kinetic energy formula (p^2)/2M, and (p^2)/2m ( where p is equal to momentum), we learn that the ratio of masses is equal to the ratio of velocities and hence energy

    so how (p^2)/2M tells us that the ratio is M:m
