An urban legend has it that the RAF was testing the windshields of their aircraft for bird strikes using a chicken cannon given to them by the USAF. The windshields kept breaking because they were using frozen chickens instead of fresh ones. Using your knowledge of physics, you would reason that the legend is
A. false - frozen and thawed chickens have the same momentum on impact.
B. true - frozen chickens are harder and come to rest in a shorter time,
C. increasing the force.
B. true - frozen chickens are harder and come to rest in a shorter time, increasing the force. (?p = F?t)
