Near-field Analysis of Superluminally Propagating Electromagnetic
... the signal is small enough, the information can be extracted in a time period much smaller than the wave propagation time. This would therefore result in information speeds only slightly less than the group speed which has been shown to be superluminal in the nearfield of the source. It has also bee ...

... 5. See answers in the exercise. 6. Initial downward velocity = 10 sin 30o = 5 m /s vY2 = 52 + 2(10)(0.3) => vY = 5.57 m/s Since the collisions are perfectly elastic, there is no energy loss. So the velocity after collision does not change. From Y to Z, time to reach max height t is given by 0 = 5.57 ...
