The distance, Δx:
k = mω2, since ω = sqrt(k/m)
ω = 2πf
A block with a mass of 0.28 kg is attached to a horizontal spring. The block is pulled back from its equilibrium position until the spring exerts a force of 1.0 N on the block. When the block is released, it oscillates with a frequency of 1.1 Hz.
How far was the block pulled back before being released? Express your answer with the appropriate units.
