harmonic motion

hello, I have some problem with this exercise. can someone help me and illustrate the solution ? thanks


the cone of a loudspeaker vibrates in SHM at frequecy of 262Hz. the amplitude at the center of the cone is A=1.5X10^-4m and t=0 and x=A (amplitude).

1) what equation describes the motion of the center of the cone ?

2) what are the velocity and acceleration as a function of time ?

3) what is the position of the cone at t=1ms ?

I see this is a high school question.

So what equation have you been taught for SHM, the sine or the cosine equation?

If you are struggling to get the information given to fit your given equation, please check the extract below as I don't think you have quite copied it correctly.

the amplitude at the center of the cone is A=1.5X10^-4m and t=0 and x=A (amplitude).
