A bomb of mass 20 kg initially at rest explodes into three pieces of mass 10 kg, m1 and m2. If the heavier one remains at rest and other move in opposite direction to each other with same speed of 10 m/s. Then find the ratio of m1 to m2.

Answer 1

the total momentum must remain at zero
so, since the moving pieces have the same speed, they must have the same mass.
