1. The problem statement, all variables and given/known data A pendulum has a period of 1.8 s. 2. Relevant equations Its length is doubled. What is its period now? The original pendulum is taken to a planet where g = 16 m/s2. What is its period on that planet? 3. The attempt at a solution T=2pi sqrt(L/g) 1.8=2pi sqrt(2L/g) I dont what Im suppose to solve for. This looks like a very simple problem, but i cant seem to figure it out. Maybe i'm over thinking it.
