(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A bicycle with tires 70 cm in diameter is traveling along a road at 25 km/hr. What is the angular velocity in radians per second?

(the answer given in the textbook is 19.8 radians per second)

2. Relevant equations

A= 1/2r^2 ∅

l = (radius)(central angle)

3. The attempt at a solution

Nvm I figured it out,

You first convert 25 km/h into cm/sec

25,000,00/60/60 = 694.5

Then, we go 2pi * 35 which gives us 219.8

We then divide 694/219.8

Which gives us 3.16

We multiply 3.16 with 2pi

And get 19.8 radians per second.
