1. If a rod travels with a speed v 0.8 c along its length, how much does it shrink? 2. Assuming that the rest radius of earth is 6,400 km and its orbital speed about the sun is 30 km, how much does earth's diameter appear to be shortened to an observer on the sun, due to earth's orbital motion? 3. A rod of length Lo moves with speed v along the horizontal direction. The rod makes and angle 0o...
