A huge cannon is assembled on an airless planet. The planet has a radius of 5.40×106 m and a mass of 3.52×1024 kg. The cannon fires a projectile straight up at 5180 m/s. What height does the projectile reach above the surface?

Explanation:

The gravitational acceleration on the planet can be calculated as follows:

Where, M is the mass of the planet and R is the radius of the planet.

The height that the projectile would reach can be calculated as follows:
