Hi, I have the following problem.

First of all, does the mass of the pendulum matter at all? and if not then I I would need to find the time in both cases and divide by 1 right? Using the equation d=v1t+0.5at^2Pendulum A is 20 cm long and has a 5g mass on it. Pendulum B is 30 cm long and has 10g mass on it. Which one has a faster period?

Time Pendulum A= 0.20 s which means that the period is 0.20 s.

Time Pendulum B= 0.25 s which means that the period is 0.25 s.

Am I right? Thank you in advance.
