A dog pushes a ball 0.25 kg with a net force of 4 N. What is the acceleration? O 3.75 m/s2
O 4.25 m/s2
O 16 m/s2
1 m/s2

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?
