The Attempt at a Solution

I'm trying to figure out how to solve this problem but I'm totally stuck and even don't know how to get started since only the amplitude is known and nothing else. I would be incredible happy, if somebody could help me with this problem.

How do you find potential energy of a harmonic oscillator at any particular displacement?
