A horizontal spring is compressed and a 4 kg block is placed on the left of the spring and a 7 kg block on the right. After the system is released from rest the 4 kg block slides to the left at 14 m/s and the 7 kg block slides to the right. The surface is frictionless. 33. The speed of the 7 kg block after it loses contact with the spring is

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?
