Derivative: position, velocity, acceleration as functions of time??? 1. The problem statement, all variables and given/known data A 1.00 kg glider attached to a spring with a force constant of 25.0 N/m oscillates on a frictionless, horizontal air track. At t = 0, the glider is passing through its equilibrium position with a velocity vx = - 0.150 m/s. (The negative sign means that the glider is headed in the direction which will compress the spring.) Find the position, velocity, and acceleration as functions of time. Include units. Think carefully about the initial phase. 2. Relevant equations 3. The attempt at a solution I am really stuck here. I am not sure how to get started with this question. Thanks for any hints or help anyone can provide.
