After converting analog signals, voice, etc to the digital realm, you are now working with 0's and 1's. These bits can be manipulated to do anything you want, reassembled and you can get some amazing outputs. Could there ever be anything more efficient with future technologies that could even make binary obsolete?

In a frictionless system of a block of mass m = 2kg attached to a spring of spring constant k = 8 N/m, the mass is displaced from the equilibrium position by x = 3m and let go with zero initial velocity, v(initial) = 0 m/s.

Answer this question :
Write an expression for the displacement x of the mass from equilibrium as a function of time. Use numerical values wherever possible.

Doesn't a jet engine have a big enough output ratio that it could produce more energy than it consumes? Wouldn't that be the same as perpetual motion?

For one of my classes in college, I need to make a model of something related to fire safety/physics. I need some info on how to make a model of a sprinkler system (what parts are needed and how to put it together). If anyone knows, or knows a website, please post. OR if you know how to do anything else related to fire safety/physics, please post as well. Thank you!
