'A block is attached to a vertical spring whose spring constant is 150 N/m. It is droped from rest with the spring at its natural length, and the block has a speed of 75.0 cm after droping a distance of 8 cm. Calculate the mass of the block.'(adsbygoogle = window.adsbygoogle || []).push({});

Now i know k = 150. v = 0.75 and x = 0.08. I also know k = mw^2. w = 2pi f but i cannot figure out how to get the angular frequency.

also...I know this one is probably very easy but i just cant figure it out:

'A block hangs from a spring and is set into vertical oscillation with an amplitude of 15 cm. During the motion, the minimum extension of the spring is 5.00 cm. Calculate the freqency of the motion.'

I know i have Xm and x, but i cannot relate them to frequency.

Any help would be greatly appriciated, thank you.
