The length of a meter stick moving at 0.95c in the direction of its length with respect to the laboratory is measured by simultaneously marking its ends on an axis which is stationary in the laboratory. As measured by clocks moving with the stick, the time interval between the making of the back mark and the making of the front mark is: 0 s 1.1 × 10-9 s 3.2 × 10-9 s 3.5 × 10-9 s 1.1 × 10-8 s
