Question

a diwali rocket is ejecting 0.5kg gas per second at a speed of 400 m/s. what is the accelerating force acting on it

Answer 1

Hi ..dear....
here is your solution...

Answer 2

Explanation:

u = 400 m/s

dm / dt = 0.5/sec

F = udm/ dt = 400 × 0.5

= 4 × 5 × 10

= 200 N

So, F = 200 N

hope this will help you
