Problem 2. Relativity the 'pole in barn.' (This is a famous paradox and you might find all sorts of variants of online. Read this version carefully and don't get confused with alternate scenarios.) A runner carries a 5-meter-long pole (as measured when the pole is at rest) and runs at an impres- sively high speed of v = The barn doors are open at both ends, so the runner goes right through. te through a 4-nmeter-long barn (as measured when the barn is at rest). (a) According to the farmer at rest with respect to the barn, will the runner and pole fit' inside the barn? Calculate the length-contracted length of the pole to answer the question. (b) According to the runner, will the pole 'fit' in the barn? Calculate the length-contracted length of the barn to answer the question. (c) Suppose the farmer attempts to close the pole inside the barn by closing both doors simul- tancously. Dcscribe what the runner will observe (in terms of when the doors close, and in what order).
