Chapter 13, Problem 13.27(choose chapter or problem)
A 2.00-kg object on a frictionless horizontal track is attached to the end of a horizontal spring whose force constant is5.00N/m. The object is displaced 3.00m to the right from its equilibrium position and then released, initiating simple harmonic motion. (a) What is the force (magnitude and direction) acting on the object 3.50s after it is released? (b)How many times does the object oscillate in 3.50s?
