A Rocket is fired vertically from the surface of Mars with a speed of 2 km/s. If 20% of its initial energy is lost due to atmospheric resistance, how far will the rocket go from the surface of Mars before returning to it ? Mass of Mars \(=6.4 \times 10^{23} \mathrm{~kg},\) Radius of Mars = 3395 km, \(\square=6.67 \times 10^{-11} \mathrm{Nm}^{2} / \mathrm{kg}^{2} .\)
- 1835 km
- 1500 km
- 1655 km
- 2020 km
Answer
(A) 1835 km
