13. a) Describe in one short sentence what is 'escape speed'? b) Starting with the conservation of energy equation, AK+AU = 0, derive an equation for the escape speed, Ve, of any object of mass m from any planet of mass Mp and radius Rp. c) As an example, calculate the escape speed from Earth. Useful constants: ME = 5.98 x 102 kg Rg= 6380km G=6.67 x 10-Nmkg 2 14. Put the 'orbital speed' and the 'escape speed' formulas next to each other and circle what is different between them. 13. a) Describe in one short sentence what is 'escape speed'? b) Starting with the conservation of energy equation, AK+AU = 0, derive an equation for the escape speed, Ve, of any object of mass m from any planet of mass Mp and radius Rp. c) As an example, calculate the escape speed from Earth.
