Determine the mass of gas ejected by the rocketduring the burn, state whether you agree with the assumption that this is negligible compared to the mass oftheorbiter.
A space orbiter of mass 2.0 × 104kg is travelling at 1500 ms−1. The engines eject hot exhaust gases at a speed of 1200 ms−1relative to the orbiter. In order to get onto the correct trajectory to dock with a satellite the orbiter fires its engines and carries out a 5.0 s burn. During this […]
