A rocket, which has a rest mass of 235,000 kg, including186,000 kg of fuel is sitting \"at rest\" in space.
When this fuel is burned iti is exhausted from the rocket witha velocity of 38,500 m/s.
For simplicity assume that all the fuel is emitted atonce!
What will be the velocity the final velocity of therocket

Solution
Since your problem statement says: all the fuel isemitted at once, this is not a variable-mass problem.
So you can simply use conservation of momentum:
Mass of rocket (m1)= 235000-186000= 49000 kg
velocity of rocket =v1
mass of fuel (m2)= 186000 kg
velocity (v2)= 38,500 m/s
v1= (m2v2)/m1
= approx. 146143 m/s
