A 6.91x106 kg spherical space ship in deep space explodes into two pieces, one 4.77 times the mass of the other.

a) Suppose the ship is initially at rest, and after the explosion the smaller piece is moving 57.6 m/s.

- Find the speed of the larger piece.

-Find the energy supplied by the explosion.

2. Relevant equations

M_{1}V_{1}+M_{2}V_{2}=0

3. The attempt at a solution

I tried establishing a ratio of the masses equals the ratio of the velocities and got -12.075 m/s for the larger piece. but got it wrong,

and the second question needs .5(m)(v^{2}) but i dont know the velocity of the heavier mass.

Is there a flaw in my reasoning

Thanks for your help
