A mass 43.7g is held against a compressed spring on a horizontal frictionless surface. The spring has a force constant 128N/m and is compressed a distance of 3.53 cm. When released the spring pushes them mass across the surface. Once the spring reaches its equilibrium position the mass separates from the spring and continues across the surface at constant velocity. Determine the final velocity of the mass when it separates from the spring (in m/s)
