It has been said that a parade of Chinese twenty a breast could march forever past an observing point. If we assume the parade to march at 3 miles per hour, with ranks 4 feet apart, what is the Chinese birth rate, in babies per hour?
ok, so far I've drawn a picture, and converted all my information, and if I'm correct, I need to use this formula: a= v^2/r
but if its a centripetal acceleration problem then where does the birth rate come into play? I'm so confused...
4mph = 1.34m/sec
4 ft = 1.22m
r= 20 people
d= 40 people
v= 1.34 m/sec
a= 1.34^2/20?
& babies per hr. = frequency
