A support crossbeam on a high speed train is made from a titanium rod that has a length of 0.650 when measured by an observer on the train. The beam is positioned such that the observer on the train measures an angle of 19 between the crossbeam and the floor of the train. At what speed would the train have to be traveling in order for an observer standing outside the train to measure the angle as 49 ? S indicates the reference frame of the observer standing outside the train and S' indicates the reference frame of the observer on the train. At what speed is the train moving when the angle between the crossbeam and the floor of the train is measured to be = 49 by an observer standing outside the train?
