22.3 rad/s

Further explanation

We will solve the question of uniform circular motion.

Given:

  • A bicycle has tires of radius [tex]\boxed{ \ R = 0.35 \ meters \ }[/tex]
  • The bicycle is traveling at a constant speed of [tex]\boxed{ \ v = 7.8 \ m/s \ }[/tex]

Question:

What angular speed are the tires rotating?

The Process:

Speed, angular speed, and radius are connected in the following formula:

[tex]\boxed{\boxed{ \ v = \omega R \ }}[/tex]

The angular speed is worked out by

[tex]\boxed{ \ \omega = \frac{v}{R} \ }[/tex]

All units are in the SI system so let us calculate the angular speed.

[tex]\boxed{ \ \omega = \frac{7.8 \ m/s}{0.35 \ m} \ }[/tex]

Thus the value of the angular velocity of the rotating tire is [tex]\boxed{\boxed{ \ \omega = 22.3 \ rad/s \ }}[/tex]

An additional question:

What is the frequency of tire rotation?

Recall this formula: [tex]\boxed{ \ \omega = 2 \pi f \ } \rightarrow \boxed{ \ f = \frac{\omega}{2 \pi} \ }[/tex]

[tex] \boxed{ \ f = \frac{22.3 \ rad/s}{2 \pi} \ }[/tex]

We get [tex]\boxed{\boxed{ \ f = 3.55 \ Hz \ }}[/tex]
