An object is hovering about the surface of the earth. It begins to experience a gravitational acceleration of 2.0 m/s2. How high is it above the surface of the earth?
After landing on an exoplanet, an astronaut constructs a simple pendulum of length 49 cm. The pendulum completes 89 full swing cycles in a time of 101 s.
What is the magnitude of the gravitational acceleration in m/s2 on the exoplanet? Give your answer to 2 decimal places.
The next two questions are going to deal with Superman’s home planet of Krypton. Here on Earth, an athletic man can do a standing jump of about 1.5 m. On the moon, where gravity is 6 times weaker, an athletic man can do a standing jump of about 9.0 m. Originally, Superman was said to be able to “leap tall buildings with a single bound”. Based on this expression, let’s assume that Superman can jump 200 m here on Earth. Using this information, what is the gravitational acceleration, g, of Krypton?

The architects working with you to plan the base need to know the acceleration of a freely falling object at the surface of the planet in order to adequately design the structures.
