Intro to Simple Harmonic Motion (Horizontal Springs)
17. Periodic Motion / Intro to Simple Harmonic Motion (Horizontal Springs) / Problem 7
A steel block is attached to a helical spring on a frictionless air track. The block is initially set to a position -A units from its equilibrium position and released from rest. Which graph illustrates the positions of the block at given time: 0, 1/4 T, 1/2 T, 3/4 T, T, and 5/4 T, where T is the natural period of oscillation?
