Find velocity of the rod and the proper length of rod

Reference no: EM13548255

A rod flies with constant velocity past a mark which is stationary in the K frame. In the K frame, it takes the rod Deltat = 20 ns to fly pass the mark. In the K' frame fixed to the rod, the mark moves past the rod in Deltat' = 25 ns. Find (a) the velocity of the rod and (b) the proper length of the rod.
