Calculating the Number of Waves Passing a Boat in 55 Seconds: Physics 11

Click For Summary

Homework Help Overview

The discussion revolves around calculating the number of waves passing a boat over a specified time period, specifically how many waves would pass in 55 seconds based on the observation of 16 waves in 38 seconds. The subject area is physics, focusing on wave motion and rates.

Discussion Character

  • Exploratory, Mathematical reasoning

Approaches and Questions Raised

  • Participants explore the calculation of wave frequency by dividing the number of waves by the time period and then applying that rate to a different time frame. Some participants question the relevance of other posts that deviate from the original problem.

Discussion Status

The discussion includes attempts to clarify the calculation method, with some participants providing their reasoning and calculations. There is recognition that the problem has been addressed, although some responses seem to stray from the main topic.

Contextual Notes

There are instances of off-topic humor and unrelated problems discussed, which may distract from the primary focus on the wave calculation. Some participants emphasize the importance of sticking to the original problem statement.

Physics 11 is so confusing ...

A Person,resting in a boat, notices that 16 waves pass the boat every 38 seconds ... HOw many waves would pass the boat in 55 seconds?

A boy does 0 homework problems in 16 minutes. How many homework problems will he complete in 1 week? :-)
 
in order to answer that you need to find howmany waves in a second (16/38) which equals to *.42* meanning there will be .42 waves passing every second. then you just multiply it by 55 (.42*55) which equals to 23.2 (23.15789473684...

He better hope that one isn't on the test! :smile:
 
hmmm the boy does 0 homework in one week, because 7 days in one week and 24 hours in one day so: 24*7=168, then 60 minutes in an hour, 60*168=10080, and he does 0 in 16 minutes so, 10080/16=630, then 630*0=0, that's it. :smile:

Yeah, but what if his rate grows exponentially? :wink:
 
well that was not part of the problem, it says he does 0 homework in 16 min, so I deduce that he does 0 in 16 min. So it cannot increase exponentially if 0=0. :biggrin:
 
okay bottom line, let's stop fooling around. :rolleyes:

16 waves x waves
----------- = ---------------
38 seconds 55 seconds


solve this

you should get
23.16 waves

tom thxs for that, but problem was all ready solved. Look above, but thxs for the try. :smile:
