On your first trip to Planet X you happen to take along a 215 mass, a long spring, a meter stick, and a stopwatch. You're curious about the free-fall acceleration on Planet X, where ordinary tasks seem easier than on earth, but you can't find this information in your Visitor's Guide. One night you suspend the spring from the ceiling in your room and hang the mass from it. You find that the mass stretches the spring by 31.5 . You then pull the mass down 11.4 and release it. With the stopwatch you find that 11 oscillations take 16.6 .
Part A What is the value of gravity? =
Part B What is the spring constant of your spring? =
