Completely OT: Simple Harmonic Motion + Oscillations

In Physics. Have zero idea how to get the 2nd part of this problem, and I cant get the 3rd without finding the 2nd. Someone wanna take a crack at it?

A 1.20 kg mass is attached to the end of a spring of unknown spring constant. The spring is compressed a distance of 0.300 meters, and when it is released, the mass oscillates horizontally on a frictionless surface. When the mass is 0.100 m from equilibrium, it is seen to be moving at a speed of 2.00 m/s. (a) What is the amplitude of the motion? (b) Find the spring constant, k. © What is the maximum speed of the mass?

I know that the spring constant equation is K.E. = 1/2kx2.
Other than that…. Haha. I apologize.

I hope you realize your asking the users of rap genius for physics help, a website filled with the laziest motherfuckers the internet has ever seen
