Universal Gravity Problems Day #2

2. Example #1
An astronaut travels to a new planet. During a test, she drops a stone from a height of 2.00m. The average fall time for the stone was s. Determine the acceleration due to gravity.

3. Example #2
Her next test was to determine the mass of the planet by first finding the radius. She did this by placing a spike in the ground and measuring the angle of the shadow at noon. She then traveled km north and performed the same experiment. Determine the radius and mass of the planet.
