A 0.064 kilogram block on a horizontal frictionless surface is attached to a spring whose force constant is 330 N/m. The block is pulled from its equilibrium position at x = 0 meter to a displacement x = +0.080 meter and is released from rest. The block then executes simple harmonic motion along the x-axis (horizontal). Compute the velocity of the block at a time t=0.20 second?
