A simple pendulum is 5.20 m long. What is the period of simple harmonic motion for this pendulum if it is hanging in an elevator that is accelerating upward at 5.90 m/s2?
The Attempt at a Solution
all I did was plug in the value of the length of the pendulum into the equation like so:
but this answer is not right? I'm so confused as to what I am supposed to do and why I am given acceleration if I dont even need it.
