How long would a meterstick appear to be if it were traveling like a properly thrown spear at 99.5% the speed of light?

Solution 25RQ Introduction: In relativistic speeds, the length of an object is appeared to decreased when the observer or the object is travelling at non-zero velocity. This phenomenon is called as “length contraction” 2 The mathematical expression for length contraction is, L = L 0 1 c2 Where, L - Length observed by the observer L - Original length 0 v - Relative speed between the observer and object c - Speed of light Step 1: In this problem, we have to find out the length of the metre scale observed by the observer. So, the actual length of the metre scale is, 0 = 1 metre Velocity with which it travels = 99.5 % of c It is nothing...
