Aplant falls from a window ledge 3.5 m above the sidewalk. how fast is the plant moving when it hits the sidewalk? a.-7.3 m/sc.-22.0 m/sb.-2.2 m/sd.-8.3 m/s 

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?
