Question from Kenzi, a student: A wheel of radius 14 inches is rotating 45°/sec. What is the linear speed in in/sec and the I already found the linear speed. I got 10.996 in/sec. I don't know how to find the angular |
Hi Kenzi,
so the wheel rotates one eights of a revolution per second.
\frac18 \frac{\mbox{revolutions}}{\mbox{second}} \times \frac{60}{1} \frac{\mbox{seconds}}{\mbox{minute}} = \frac{60}{8} \mbox{RPM.}
