There are two reference frames K and K ', the relative velocity of which is unknown. Parallel to the x-axis, the rod moving with respect to the system K at a speed of 0.1 s has a length l = 1.1 m in this system. In the system K, the length of the rod is l = 1 m. Find the velocity of the rod vx in the system K and the relative velocity systems v0.

A detailed solution with a brief record of the condition, formulas and laws used in the solution, the derivation of the calculation formula and the answer.
