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 ( Ο t β Ξ± ) where Ξ± 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 Ο ? what is the phase shift?
