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

Suppose that a mass of 2 kg is attached a spring whose spring constant is 50. the system is damped such that b = 12 . the mass is set in motion with an initial velocity of -8 m/s at a position 0 meters from equilibrium. set up and solve a differential equation that models this motion. write your solution in the form a cos ( ω t − α ) where α is a positive number. use your solution to fill in the information below: what is the amplitude of the motion? what is the value of ω ? what is the phase shift?
