Homework #5 Due in recitation week of April 25, 2011 1. Some time, in the not too distant future, relativistic Purple Line trolleys will be zipping across our campus. Consider two such trolleys as they pass by the Stamp Union. Trolley 1 is traveling at 0.6c to the right (increasing x) and Trolley 2 is traveling at 0.8c to the left as measured by someone on the steps of the Stamp Union. Each trolley is 10m long in its rest frame (back at the Trolley round house). Define event #1 to be the front of the trolleys pass each other, and define event #2 to be the back of the trolleys pass each other. Stamp Union Trolley 2 Trolley 1 x v 1 =0.6c |v 2 |=0.8c A. How long is each trolley in the Stamp Union frame? B. Suppose Event #1 occurs at (x=0, t=0) in the Stamp frame. When and where does event #2 occur in the Stamp frame. C. Now calculate the coordinates of these events in each of the trolley frames. D.
