A mass of 2 kg is attached to a spring which has a spring constant k of 50 N/m. The spring/mass assembly is horizontal and is supported on a frictionless, what else? table. The weight is pulled ( by You) to the right until the spring is stretched .2 m. What is the force the spring puts on the mass. What is omega? What is the potential energy stored in the spring (g and h don't enter into this at all). What is the acceleration of the mass when you let go. What is the maximum KE of the mass. What is the maximum speed and where does it occur? Let x = 0 when the spring is relaxed. Assume the spring's mass is negligible.
