Problem: Spacecraft have been sent to Mars in recent years. Mars is smaller than Earth and has correspondingly weaker surface gravity. On Mars, the free-fall acceleration is only 3.8m/s2.
Part A: What is the orbital period of a spacecraft in a low orbit near the surface of Mars?
I need help to find the orbital period of a spacecraft in a low orbit near the surface of Mars and assume the radius of the satellite's orbit is about the same as the radius of Mars itself, rMars = 3.37×106m.
