A 175-g glide Rona horizontal, frictionless airbricks attached to a fixed ideal spring with force constant 155

Question:

A 175-g glide Rona horizontal, frictionless airbricks attached to a fixed ideal spring with force constant 155 N/m. At the instant you make measurements on the glider, it is moving alO.815 m/s and is 3.00 cm from its equilibrium point. Use energy conservation to find
(a) The amplitude of the motion and
(b) The maximum speed of the glider.
(c) What is the angular frequency of the oscillations?
