Hello, can anybody help me ? one question about simple harmonic oscillation

[wowolala]

1. Homework Statement [/b]

Let Z(t)=(3/4)Sin(2π/3t) be the equation for a SHO in the Z diection about z=0.

1. what are the amplitude, phase, frequency, angular frequency and period of this SHO?

2. what is the maximum velocity? what is the maximum acceleration?

3. when Z= 3/4, what are the velocity and acceleration?

4. when z=0, what are the velocity and acceleration?

Could someone solve all question for me, i am so confused in this part .

thx so much

You must show some attempt, however bad you think it is. Write the meanings of the various symbols in SHM, and then try to see what is given here. You WILL get help.
