The spaceship Intergalactica lands on the surface of the uninhabited Pink Planet

Question

The spaceship Intergalactica lands on the surface of the uninhabited Pink Planet, which orbits a rather average star in the distant Garbanzo Galaxy. A scouting party sets out to explore. The party's leader–a physicist, naturally–immediately makes a determination of the acceleration due to gravity on the Pink Planet's surface by means of a simple pendulum of length 1.13 m. She sets the pendulum swinging, and her collaborators carefully count 107 complete cycles of oscillation during 204 s. What is the result?

Explanation / Answer

g = 4²L/T² = 4²*1.13/[204/107]² = 12.26 m/s²
