Question

Q. Prove that the velocity of a rocket of mass ;mo' at the instant when its mass is m is given by v='vo'+ u ln mo/m where vo is the initial velocity of the rocket and u is the velocity of the exhaust gases relative to the rocket Ans correctly...And pls no spamming.I will even follow the ryt ans

Answer 1

Answer:

they out Rockets journey Momwntum is conserved .

so if MV = MoVo

Dv/Dm can be equated to Ratio of Mo/V

and Log come because residual mass is reacted to gain in velocity by burn
