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?(adsbygoogle = window.adsbygoogle || []).push({});

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
