Please describe step by step for each step

In a physics lab, you attach a 0.202 kg air-track glider to the end of an ideal spring of negligible mass and start it oscillating. The elapsed time from when the glider first moves through the equilibrium point to the second time it moves through that point is 3 s after starting the oscillation from an initial stretch of 3. (a) What is the angular frequency of this oscillation? (6 points) (b) Find the spring's force constant. (6 points) c) What is the maximum potential energy of the spring? (7 points) d) What is the speed of the mass as it passes through the equilibrium point? (6 points) X
