<PRE><B>Question 817809</B>
bike linear speed:
s = 35 miles/hour * (1/60 hr / min) * (5280 ft / mile) * (12 in / ft)
s = 36960 in/min
---
wheel circumference:
c = 2 pi r
c = 2 pi 13
c = 81.681409 in/rev
---
wheel angular speed:
a = s / c
a = 36960 in/min / 81.681409 in/rev
---
answer:
a = 452.5 rpm
