Rotational Velocity Question - I think?

Homework Help Overview

The problem context involves a hypothetical scenario where a parade is marching at a specified speed, and the question relates to calculating a birth rate based on the parade's characteristics. The subject area touches on concepts of motion and possibly rates of change.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants discuss the relevance of centripetal acceleration and the formula a = v^2/r, questioning its application to the problem. There is confusion about how the birth rate relates to the motion of the parade. Some participants suggest that the problem may not involve circular motion at all.

Discussion Status

The discussion is ongoing, with participants expressing confusion and questioning the initial assumptions about the problem setup. Some have pointed out potential flaws in the reasoning, while others are exploring different interpretations of the problem.

Contextual Notes

There is mention of the impracticality of the scenario, particularly regarding the assumption that babies can walk and the implications of historical birth rates. Participants are grappling with the lack of clarity in the problem statement.

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

sorry, the title is wrong. =[

If you've figured out that the title is wrong, I hope you've also figured out that v^2/r has nothing to do with the problem.
 
circles have nothing to do with this, in the time taken for 1 row of people to go past the observation point, 20 more babies need to be born, little problem that babies can't walk (so it may be you have to take into account a birth rate from a few years ago, so you can work on number of new walking chinese people) sounds a bit pointless to me
