Consider a ball of mass m-0.4 kg attached to one end of a spring of spring constant k-1.0 N/m. The other end of the spring is hung from the ceiling and the ball is allowed to come to rest at its equilibrium point. The ball is then pulled downward a distance y--0.20 m below the equilibrium point and released. There is a damping force on the ball of F--b where b-0.04 Ns/m and where v is the speed in the vertical direction. Write a program using PhilsPlot which plots the height of the ball y (on the vertical axis) as a function of time (on the horizontal axis). Plot the motion for at least 20 seconds. The following might help you formulate your approach. F--ky-b dy vd The initial velocity is (0)-0 m/s and the initial position is y(0)--0.20 m
