A 6000 kg rocket is set for vertical firing

Asked by admin @ 17/08/2021 in Physics viewed by 323 People

A 6000 kg rocket is set for firing if the exhaust speed is 1000 m/s How much gas must be ejected each second to supply the thrust needed to overcome the weight of rocket

Answered by admin @ 17/08/2021

Thank you for asking this question.i hope my answer will help you
thrust is calculated through following formula:
f=u*(dm/dt)
where:
f=thrust
u=relative
f(thrust)=f(weight)
=1000*(dm/dt)=mg=6000*10
=dm/dt=60
so the gas ejected is 60km/sec

Ask if you have any confusion regarding this numeric solution.
