Hi there!
I recently received the following task.
A small block is attached to an ideal spring and is moving in SHM on a horizontal, frictionless surface. The amplitude of the motion is 0.240 m and the period is 3.08 s.
a. What is the acceleration of the block when x = 0.160 m?
I had difficulty solving this task. I will be very grateful for your help.

What equation(s) have you learned that would apply to simple harmonic motion, that depend on amplitude, position and period?

(people aren't going to do the work for you)

I decided to ask this question at https://plainmath.net/49881/a-small-block-is-attached-to-an-ideal-spring-and There users gave me an explanation and solution. Can you please check if everything is correct in the calculations? 

In fact, I have a major difficulty with SHM, because I don't understand how it affects and how to start calculating. Most likely, I first need to determine the angular frequency. Right?

If your equation has frequency in it, yes. What equation are you thinking of using?
