Find the angular frequency w of the resulting oscillatory motion.

For this question, I got 10.646. Is this correct?

What is the maximum speed of the block?

Would I need to find the amplitude to multiply by w to get the maximum speed? If that's the case, how would I find the amplitude?

Thank you!

**drwls**, Tuesday, February 19, 2008 at 2:54pmThe angular frequency w is sqrt (k/m). sqrt (82/.75) = 10.456 sec^-1

The maximum speed V can be obtained from the stored potential energy is the spring before release.

(1/2) k X^2 = (1/2) m V^2

V = sqrt (k/m) X = w X

where X is the 0.12 m displacement
