An air-track glider attached to a spring oscillates between the 9.00cm mark and the 54.0cm mark on the track. The glider completes 7.00 oscillations in 34.0s . What is the period of the oscillations? What is the frequency of the oscillations? What is the angular frequency of the oscillations? What is the amplitude? What is the maximum speed of the glider?
