The Amplitude (cm.)

The Period (s.)

The Spring Constant (N/m)

The maximum speed (cm/s)

The total energy (J)

The velocity at t=0.40 s. (cm/s)

I need your help, please help me guys. Thanks!

**Charlie**, Wednesday, December 16, 2009 at 5:11pmi figured out the amplitude and the period, i just dont kno how to get to the other 4 with using simple harmonic motion equations

**bobpursley**, Wednesday, December 16, 2009 at 5:21pmspring constant:

Period=2PI sqrt (m/k)

max speed= 2*2

energy= 1/2 k x^2

velocity= 2*2 sin2t

**bobpursley**, Wednesday, December 16, 2009 at 5:32pmThen you are in great trouble in Physics B. You need to review periodic motion in your text.
