Homework Statement
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)
Homework Equations
A= 1/2r^2 ∅
l = (radius)(central angle)
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.
