How does light travel? A . light only travels in a vacuum and travels faster when the sound source is moving
B. Light only travels in a medium and light travels faster than he sounds source is stationary
C. Light can travel in a vacuum Anne the speed varies This depending on whether the source is moving or stationary
D. It can travel in the air or a vacuum and the speed is constant whether the light source is stationary or moving ​

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?
