2. Alice moves away from Bob with a speed 1' (relative to Bob) such that Bob sees her clock tick at half the rate of his clock' a) What is the speed, 11'? How fast does Alice see Bob's clock running compared to her clock? b) Suppose Alice holds a rod with a length of 5 In in her inertial frame. \\Yhat length does Bob see? You can assume the rod is held parallel to their relative velocity. e) Bob also holds a red but the rod is not necessarily parallel to the relative velocity between Alice and Bob. Alice says the rod is 3 in. What are the possible lengths that Bob could observe (give a range)
