After landing on an unfamiliar planet, a space explorer constructs a simple pendulum of length 55.0 cm. The explorer finds that the pendulum completes 93.0 full swing cycles in a time of 129 s.

What is the value of the acceleration of gravity on this planet?

The value of the acceleration of gravity on this planet is .  

Explanation:

Given that,

Length of the simple pendulum, l = 55 cm = 0.55 m

The explorer finds that the pendulum completes 93.0 full swing cycles in a time of 129 s. The time period is given by :

We need to find the value of the acceleration of gravity on this planet. The time period in case of simple pendulum is given by :

So, the value of the acceleration of gravity on this planet is . Hence, this is the required solution.
