Question

The mass of gas emitted from the rear of toy rocket is initially 0.2kgs.if the speed of the gas relative to the rocket is 4kg.what is the initial Accleration of the rocket? ​

Answer 1

Answer:

The acceleration of the rocket in .

It is given that,

The rate of mass of the gas emitted from rear of a rocket is  initially 0.1 kg/s

Speed of the gas relative to the  rocket is 50 m

Mass of the rocket, m = 2 kg

Mass per unit time is given by :

t = 20 seconds

Let a is the acceleration of the rocket. It is given by :

Initial speed, u = 0

So, the acceleration of the rocket in . Hence, this is the required solution.
