(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A rocket for use in deep space is to have the capability of boosting a total load (payload plus the rocket frame and engine) of 3.10 metric tons to a speed of 10 000 m/s.

(a) It has an engine and fuel designed to produce an exhaust speed of 2000 m/s. How much fuel plus oxidizer is required?

2. Relevant equations

P=mv

3. The attempt at a solution

P = mv

P = (3.10 metric tons) (10,000 m/s) = 31,000 metric tons m / s

mv (total) = mv (fuel)

31,000 metric tons m /s = m (2000 m/s)

m= 15.5 metric tons

^^ This is not the correct answer.

I just don't know where to go with this anymore...
