Using conservation of momentum:
Differentiate with respect to time:
Now plug in the given values at time , then solve for the acceleration of the rocket .
The mass of gas emitted from the rear of the toy rocket is initially 0.1 kg/s.If the speed relative to the rocket is 50 m/s, and the mass of the rocket is 2 kg.What is the initial acceleration of the rocket?
In this question How can i use the conservation of momentum? Please help>>>>>
