A rocket is fired ‘vertically’ from the surface of mars with a speed of 2 km `s^(–1)`. If 20% of its initial energy is lost due to martian atmospheric resistance, how far will the rocket go from the surface of mars before returning to it ? Mass of mars = `6.4 xx 10^(23)` kg, radius of mars = 3395 km, G = `6.67 xx 10^(-11) N m^(2) Kg^(-2)`.

Explanation

495 KM
