Question

escape velocity of mars ?​

Answer 1

Explanation:

Mmars = 6.42 x 10²³ kg

Rmars = 3398 km = 3.398 x 10⁶ m

Vescape = (2 x 6.67 x 10-11 N m² kg-³ x 6.42 x 10²³ kg / 3.398 x 10⁶ m)0.5

Vescape= 5.02 x 10⁴ m/s = 5.02 km/s

Hope you got your answer

Have a great day ahead

Answer 2

Explanation:

In both case, it is possible to us aero braking at arrival, which improves the mass budget. however, mars and even more so venus are large planets, with escape velocities of 5.02 km s-1, respectively. the escape velocities of mars is even larger than that of mercury (4.26 km s-1)
