Question is:(adsbygoogle = window.adsbygoogle || []).push({});

A particle hangs from a spring and oscillates

with a period of 0.4 s.

If the mass-spring system remained at rest,

by how much would the mass stretch it from

its normal equilibrium position? The acceler-

ation of gravity is 9.8 m/s2.

And the choices are:

1. 0.158872 m

2. 0.0794358 m

3. 0.124777 m

4. 0.317743 m

5. 0.0397179 m

6. 0.635486 m

I tried answer #6 but it wasn't right. I used W=SqRt of K/M
