My back-of-the envelope math says no: 12 stories, say 12 feet/storey as a round number. 144 feet. s = 16 t**2, so t**2 = 9, t = 3, a 3 second fall v = 32 t so it is doing 96 feet/second when it hits, about 65 miles an hour. -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
