Review I Constants I Periodic Table PartA A block with a mass of 0.30 kg is attached to a horizontal spring. The block is pulled back from its equilibrium position until the spring exerts a force of 1.1 N on the block. When the block is released, it oscillates with a frequency of 1.2 Hz. How far was the block pulled back before being released? Express your...
