2. conduct research to learn more about your proposed solutions. be sure to look up information about
cost, safety, reliability, and social or cultural implications when applicable. what are the pros of each
solution? what are the cons of each solution?

Holes drilled several kilometers into earth’s crust provide direct evidence about earth’s interior in the form of

The discovery of the electron as a subatomic particle was a result of

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?
