Special relativity tells us that someone sprinting will shrink, or undergo length contraction, along the direction of motion relative to someone at rest. The world's fastest sprinters, like Usain Bolt, can reach speeds near 13.0 m/s. How fast would they have to run so that their length contraction was (a) equal to the width of a human hair (50.0 μm) and (b) equal to the width of an atom (1.00 x 10-10 m)? Assume the width of the sprinter's body at rest is 25.0 cm. (a) Number Units (b) Number i Units
