Special Relativity question: Anne and Bob are driving along a long straight road. While passing a tree, Bob sets it on fire. Anne is approaching the tree with speed 0.6c; in Anne's frame of reference, Bob is exactly halfway between her and the tree when the first light from the fire reaches Anne's car. How fast is Bob driving with respect to the ground? Anyone know how to start this question? I'm having a lot of trouble setting it up...
