Question

A 3000 kg rocket is fired if the exhaust speed is 500 m/s how much gas must be ejected per second to supply the thrust needed

Answer 1

Answer:

This question will be solved by Law of conservation of momentum.

The minimum velocity can be gained by rocket is 1 m/s. So

3000kg×1m/s=x kg×500m/s

x = 6kg.

Hence 6kg of gas must be burned per second.

Answer 2

Explanation:

सिक्स मीटर पर सेकंड 6 m/s2
