Problem: A block with mass .382kg is attached to a horizontal spring with spring constant k=1.28 N/m on a frictionless surface. The block is pulled .753m from equilibrium and released.
Part I: What is the amplitude of the block's motion?
Part II: What is its period?
Part III: How long after release does the block take to first return to its equilibrium position?
Part IV: What is its speed at that position?
I need proficient help in the above problem. Thanks in advance.
