Question

A cracker rocket is ejecting gases at a rate of 0.05kg per/sec with a velocity 400 m per/sec . Find the acceleration force on the rocket

Answer 1

heya di

The answer of ur question is

Ejecting gas at 0.05 kg per sec
velocity =400 m per /sec

so dm /dt = 0.05

F = V × dm /dt
= 400 × 0.05
=20 Newton


hope it helps

Answer 2

Hey mate ^_^

=======
Answer:
=======

Momentum of the ejection gases = mass × velocity

           =0.05 × 400

           =20kgm/s

           =20N

Hence the acceleration force of the rocket is 20 N
