The discussion revolves around calculating the linear speed of a vehicle based on the diameter of its wheels and their rotational speed. The original poster presents a specific problem involving a wheel diameter of 1.075 meters and a rotation rate of 300 revolutions per minute (rev/min).
The discussion is ongoing, with participants sharing their calculations and questioning the accuracy of their results. Some guidance regarding significant figures is mentioned, and there is a comparison of answers derived from different sources, indicating a productive exchange of ideas.
There are references to discrepancies between participants' calculations and those provided in a textbook, raising questions about the definitions and relationships between linear speed and other speed measures. The discussion also highlights potential confusion regarding the application of formulas in different contexts.
Your answer looks good to me. If your entering your answers on webassign, beware of the number of significant figures you include.dan_bighit said:no don't what that is, but i do know what angular velocity and angular acceleration is.
i thought linear speed was diameter(metres) x pie x rev/min x 60 / 1000 would give you the speed in km/h
which would give the answer 60.79 km/h
but turns out its wrong.
Yes, just out of interest, what speed does your book return?dan_bighit said:the book I am reading must be wrong then, is linear speed just the same as speed then
