Simple Harmonic Motion

  1. Jun 23, 2006 #1
    Please help with the following problem:

    A 0.1 kg block rests on a level surface and is attached to a horizontally aligned spring with a spring constant of 32 N/m. The block is initially displaced 4 cm from the equilibrium position and then released to set up a simple harmonic motion. A frictional force of 0.3 N exists between the block and the surface. What is the speed of the block when it passes through the equilibrium position after being released from the initial 4 cm displacement point?
