$35\text{'}784$km

Using the space elevator, you decide to bring your spacecraft at an altitute of ${55}^{\text{'}}000km.$ Once there, you simply

release the spacecraft.

$5-$ What is the speed of the spacecraft just after the release $($in $k\frac{m}{s})?$

$11\mathrm{.}19$

$6-$ What is the $v$ you need to provide to your spacecraft in order to reach the desired hyperbolic departure excess

velocity $($in $k\frac{m}{s})?$

$7-$ How much propellant $($in $kg)$ will you have to use to provide that $v?($Isp$=350$s$)$
