A rod moving in the positive x direction is measured by a stationary observer to have a length of 10.0meters and to be oriented at an angle of 70.0 degrees with respect to the positive x axis. A second observer moving adjacent to the rod and parallel to the rod%u2019s motion, in the positive x direction, measures the rod to be oriented at 5.00 degrees with respect to the positive x axis.

a. Find the speed of the second observer as measured by the stationary observer.
