Plans are in place for crewed missions beyond Low Earth Obit and the Moonwards Mars. A new rocket
has been designed for this mission. The rocket has a mass of 3.0 20 kg and can exert a thrust torce)
3520" N The rocket has been designed to have the stages so some parts can bejenisoned her the
rocket launch
a ta rocket is to escape the gravitational atraction of Earth must accelerate and reach what is termed
te escape verbory of 20.000 km
What is the intal upwards acceleration of the rocker? Show your workings
4 mars
Assuming the force remains constant, explain why a multistage rocket can reach escape velocity
more easy than a single stage rocket
