welcome to pf!
hi hopperd! welcome to pf!
it's shm, so write a differential equation, and solve it with the given initial conditions …

Thanks,
Thats the problem. I have tried 3 diff equations, and get the same answer, but it's the wrong one. So I must be missing something. What equation would you use?
