Answer: 56.718 min</h2>
Explanation:
According to the Third Kepler’s Law of Planetary motion<em> </em><em>“The square of the orbital period of a planet is proportional to the cube of the semi-major axis (size) of its orbit”.
</em>
In other words, this law states a relation between the orbital period  of a body (moon, planet, satellite) orbiting a greater body in space with the size
 of a body (moon, planet, satellite) orbiting a greater body in space with the size  of its orbit.
 of its orbit.
This Law is originally expressed as follows:
 (1)
    (1)
Where;
 is the Gravitational Constant and its value is
 is the Gravitational Constant and its value is  
 is the mass of Mars
 is the mass of Mars
 is the semimajor axis of the orbit the spacecraft describes around Mars (assuming it is a <u>circular orbit </u>and a <u>low orbit near the surface </u>as well, the semimajor axis is equal to the radius of the orbit)
  is the semimajor axis of the orbit the spacecraft describes around Mars (assuming it is a <u>circular orbit </u>and a <u>low orbit near the surface </u>as well, the semimajor axis is equal to the radius of the orbit)
If we want to find the period, we have to express equation (1) as written below and substitute all the values:
 (2)
    (2)
 (3)
    (3)
 (4)
    (4)
Finally:
 This is the orbital period of a spacecraft in a low orbit near the surface of mars
    This is the orbital period of a spacecraft in a low orbit near the surface of mars
