You're on planet YZ and an astronaut observes that a 1.0 m long pendulum has a period of 1.50s. What is the freefall accerlerttion on YZ? I know the answer is 17.6 because I worked it backwards but if the answer was given, I wouldn't know how to change the variables aroundthat's what I need help with
Answers:
1.003 m/s^2
26.4 m/s^2
17.6 m/s^2
0.23 m/s^2
Could someone direct me how to set this up or give me any assistance, please?
