Professional Application It is possible for the velocity of a rocket to be greater than the exhaust velocity of the gases it ejects. When that is the case, the gas velocity and gas momentum are in the same direction as that of the rocket. How is the rocket still able to obtain thrust by ejecting the gases?
Step-by-step solution In this problem we have to identify that is the velocity of rocket can be greater than the exhaust velocity of the gases its ejects and by considering of the cases explain how is the rocket still able to obtain thrust by ejecting the gases. Step 1 of 2 The relation between the escape velocity and the velocity ofthe rocket v is, Here is the mass of gas and is the mass of rocket. Now, if , then, So, the mass of gas will not at all be negligible compared to the rocket.
