A block rests on a frictionless horizontal surface and is attached to a spring. When set into simple harmonic motion, the block oscillates back and forth with an angular frequency of 2.5rad/s. The drawing shows the position labeled "x= 0 m" where the spring is unstrained. The drawing also shows a small bottle located x = 0.17 m to the right of this position. The block is pulled to the right, stretching the spring by x₀ = 0.05 m, and is then thrown to the left. In order for the block to knock over the bottle, it must be thrown with a speed exceedingv₀. Ignoring the width of the block, findv₀.
