Question

A wheel of radius 30 cm is rotating at a rate of 2.0 revolutions every 0.080 s. (a) Through what angle, in radians, does the wheel rotate in 1.0 s? (b) What is the linear speed of a point on the wheel's rim? (c) What is the wheel's frequency of rotation?

Step 1

1 of 7**Given:**

Radius of the wheel $\,\rightarrow\,$ = $r$ = $30.0\text{ cm}$

Rate of rotation $\,\rightarrow\,$ $2.0\text{ rev}/0.08\text{ s}$

Time interval $\,\rightarrow\,$ $t$ = $1.0\text{ s}$

We have a wheel of a known radius and rate of rotation. We are asked to determine its *angular displacement* in a given time interval. We are also asked to determine the *linear speed* and *frequency of rotation* of the wheel.
