## xkat 2 years ago Suppose the speed of light in a vacuum were only 25.0 mi/h. Find the length of a bicycle being ridden at a speed of 22.0 mi/h as measured by an observer sitting on a park bench, given that its proper length is 1.78 m.

$L'=L\sqrt{1-v^2}$WHere v is measured as a proportion of the c. $L'=1.78\sqrt{1-(\frac{22}{25})^2}$I won't insult you intelligence- you can use a calculator
