in a physics lab, you attach a 0.200 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 2.60 s.

the best answer for these questions would be:
