The distance, Δx:

$\overline{){\mathbf{\u2206}}{\mathbf{x}}{\mathbf{=}}\frac{\mathbf{F}}{\mathbf{k}}}$

k = **mω**^{2}, 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.

|Δx| =
