Determine the velocity required for a moving object 2.00 x 10^4 m above the surface of Mars to escape from Mars's gravity. The mass of Mars is 6.42 x 10^23 kg, and its radius is 3.40 x 10^3 m.

Therefore the escape velocity from Mar's gravity is m/s.

Explanation:

Escape velocity: Escape velocity is a the minimum velocity that a object needs to escape from the gravitational field of massive body.

Escape velocity

G=Universal gravitational constant = 6.673×10⁻¹¹N m²/Kg²

M= mass of Mars = 6.42×10²³ kg

R = Radius of the Mars = 3.40×10³m

The escape velocity does not depend on the velocity of a object.

            m/s

Therefore the escape velocity from Mar's gravity is m/s.

im sorry i dont know

i need with 1.3.2 investigate cycling o2 and co2 apex

we need to see it
