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

A crewed mission to Mars would involve a spacecrat that would intalyorbit Mars at a height of 210
makes 62 minutes to Orbit Mars once
Given that the radius of the Mars is 3390 km and assuming a circular orbit, what is the orbital
speed of the spacecrat around the centre of Mars Show your workings

Explain why the orbit of the spacecraft indicates that an unbalanced force is acting on
