A 1.95 kg object on a frictionless horizontal track is attached to the end of a horizontal spring whose force constant is 4.65 N/m. The object is displaced 4.29 m to the right from its equilibrium position and then released, which initiates simple harmonic motion. What is the magnitude of the force acting on the object 3.55 s after it is released? Answer in units of N. 007 (part 2 of 2) 10.0 points How many times does the object oscillate in 3.55 s? Answer in units of turn
