/sci/ please help!!!!

1. Two simple pendulum having the same length swing with angular displacements 20° and 10° respectively. Which of them moves faster?


2. When an object simply hangs at rest on a spring, F=kΔL=mg. If an unknown mass stretches an unknown spring by 0.123m, what is the period when the mass oscillates in SHM on the end of the spring?

Have to be more specific. What is the definition of 'faster' here?
Highest top speed? That would be the 20 degree one.
Highest frequency/time of passing over the middle? The 10 degree one.
Highest mean speed? No clue honestly, probably the 10 though.

I'm sorry, I'm referring to the top speed >_<

I've already answered 1 but I'm still having problems with answering #2 :/

Thanks for replying~

Someone please help me with #2.. : When an object simply hangs at rest on a spring, F=kΔL=mg. If an unknown mass stretches an unknown spring by 0.123m, what is the period when the mass oscillates in SHM on the end of the spring?

I wish I could tell you, but I don't know enough math to tell you.
