Energy released by spaceship explosion

  1. Oct 29, 2008 #1
    1. The problem statement, all variables and given/known data
    A 6.91x106 kg spherical space ship in deep space explodes into two pieces, one 4.77 times the mass of the other.
    NOTE: the velocity needs magnitude and direction (given by the sign).

    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. 12.075 m/s
    - Find the energy supplied by the explosion.


    2. Relevant equations

    .5mv^2

    3. The attempt at a solution
    I tried adding the .5mv^2's of both the masses but the answer comes out to be wrong

    THank you
