While traveling in a train at half the speed of light, you notice time slowing and distances shrinking outside. Your friend on the platform notices your clock ticking slower and the train appearing shorter. Both perspectives, based on relativity, reveal the dramatic effects of traveling at such high speeds, demonstrating time dilation and length contraction, which are central concepts in relativity theory.

Alan and Barry are at Six Flags riding the bumper cars, as shown in the diagram. (a) At the instant shown, Alan begins to accelerate at 1.25 m/s2 to a speed of 4.0 m/s and then continues at constant velocity until he hits Barry. Calculate the total time it takes
