The cart was sitting still at the original's point for 5 seconds, then was moving with constant speed away from the origin in the positive direction with the speed of 20 m/s for 3 seconds, then made a stop for 2 seconds turned around and moved back to the origin with acceleration 2 m/s2. Answer the following questions on a paper and upload a picture. Calculate how far did the cart move in positive direction first

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?
