You look through a camera toward an image of hummingbird in a plane mirror. the camera is 4.30 m in front of the mirror. the bird is at camera level, 5,000 m to your right and 3.30 m from the mirror. for what distance must you focus the camera lens to get a clear photo of the image : that is , what is the distance between the lens and the apparent position of the image ?

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?
