Asked by somebody

A rocket expels gas at the rate of 0.5kg/s.If the force produced by the rocket is 100N,what is the velocity with which the gas is expelled.
Answered by MathMate
Force = rate of change of momentum

Propelling force=100N
m (of propelling agent)=0.5 kg / s
velocity=v
100 N=0.5 kg/s *v
=>
v=100/0.5 m/s
=200 m/s

V=200m/s

F=ma
F= m*v/t
F=(m/t)*v
100/0.5=v
200m/s=v
