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 1.02 m. She sets the pendulum swinging, and her collaborators carefully count 106 complete cycles of oscillation during 212 s. What is the result?

Explanation / Answer

Solution:simple pendulum of length 1.02 m

She sets the pendulum swinging, and her collaborators carefully count 106 complete cycles of oscillation during 212 s

g = 4²L/T² = 4²*1.02/[212/106]² = 10.05 m/s²
