1. The problem statement, all variables and given/known data An astronaut notices that a pendulum which took 2.46 seconds for a complete cycle of swing when the rocket was waiting on the launch pad takes 1.26 seconds for the same cycle of swing during liftoff. What is the acceleration of the rocket?(Hint: Inside the rocket, it appears that g has increased.) 2. Relevant equations T=(2pi)sqrt(L/g) 3. The attempt at a solution I know I am supposed to use the above equation, but I don't know how to use it to solve for acceleration. Using g=9.8m/s^2 and the initial period, I solved for L and got 0.621m. Do I even need to do that for this problem? The fact that the problem said that "g" increased within the rocket is what confuses me the most. Am I solving for a new/increased value of "g" and using that as acceleration? If so, when I solved the problem this way, I got g=15.4 m/s^2 (using the second period and 0.621m as L), but this was incorrect. I really need help with this problem as my teacher disabled the hints option. Thanks in advance.
