Document Summary
Linear kinematics: displacement, velocity, acceleration, applied examples. Use this as a reference in the future weeks; always end with a correct unit in addition to your numerical answer in problems! = (cid:448)elo(cid:272)ity / ti(cid:373)e = v2 v1 / t. ~31 active gps satellites: maintained by the us air force, anyone with a gps device can receive signals from. The satellites" orbits are arranged so that, at any time, there are at least four satellites above the horizon anywhere in the world. http://www. abc. net. au/science/articles/2009/06/18/2602027. htm.
