In this example, we're going to look at simple harmonic lotion, maybe a little bit of a different setup that you said between.
00:13
It should be vertical, sorry, put the ball on top of it.
00:18
And what we're going to do, we're going to pull it 20 centimeters to the side, and then we're going to let it go.
00:28
Okay, and you want to find the spring constant of the system.
00:32
Find a period of oscillation.
00:34
There, so the data from the problem is the mass of the system.
00:39
Ball, i'll call it m equals 2 .0 trillion.
00:45
And we're gonna pull it 20 centimeters to the side, so i'll call that my x distance and that's gonna be my total, and that's my amplitude, total, equals 20 centimeters.
01:02
Alright, and we know that the force for fire to do that is 8 minutes.
01:08
Alright, so we're going to use this information first to find our spring constant.
01:13
Alright, so we'll use hook -law.
01:16
F equals kx.
01:21
Negative kx.
01:23
That negative distance here is so i'm looking for back to you, so i guess i'll turn that into a positive.
01:30
Alright, so our spring constant equals x over x...
