Question

A rocket burns fuel
at the rate of 20kgs
I and reject it when
a a velocity of 5-ox 10° 3m 1
calculate thee thrust exerted
e rock​

Answer 1

Overall momentum of the system is conserved.

Therefore, change in momentum of the rocket will be equal to that of the fuel.

Change in momentum of the fuel will be

Δmv = 10000

Hence, change in momentum of the rocket will also be:

△P = 10000

Thrust force F = △p/△t

F = 10000 N
