Update:

A spacecraft consists of a 32,500 kg engine and a 12,600 kg nosecone. The rocket is initially traveling at 22,000 m/s when the engine and the nosecone separate. After the separation, the engine is moving at 18,900 m/s. How fast is the nosecone moving?

Is this a conservation of mechanical energy problem?

Please provide the answer and the steps you used to get the answer, thanks!

    No. Conservation of momentum.

    P1 = P2

    (32500 + 12600)*22000 = 32500*18900 + 12600*v

    Solve for v
