Radial Velocity in Elliptic Orbit given Radial Position and Angular Momentum Solution

Follow our step by step solution on how to calculate Radial Velocity in Elliptic Orbit given Radial Position and Angular Momentum?

FIRST Step Consider the formula

v r = \frac{h e}{r e}

Next Step Substitute values of Variables

∴

v r = \frac{65750km²/s}{18865km}

Next Step Convert Units

∴

v r = \frac{6.6E+10m²/s}{1.9E+7m}

Next Step Prepare to Evaluate

∴

v r = \frac{6.6E+10}{1.9E+7}

Next Step Evaluate

∴

v r = 3485.2902199841m/s

Next Step Convert to Output's Unit

∴

v r = 3.4852902199841km/s

LAST Step Rounding Answer

∴

v r = 3.4853km/s
