1. The problem statement, all variables and given/known data An air-track glider is attached to a spring. The glider is pulled to the right and released from rest at t=0 s. It then oscillates with a period of 1.5 s and a maximum speed of 40.4 cm/s. What is the amplitude of the oscillation? 2. Relevant equations x=Acos(wt+ro) 3. The attempt at a solution I really don't know how to start this problem because angular speed is not given and the length the air glider travels is not given either.
