Asked by Ellie
(The number of times a bicycle tire rotates in a given time period is directly related to the distance traveled in that time period. Consider the following scenarios.)
1. Calculate the angular speed of a bike with 26-inch tires rotating at 200 revolutions per minute. Express your answer in radians per minute. Use π = 3.14.
Here's what I got:
angular speed= (200 revs•2π/60 radians per second) =20.94 radians per second
(20.94 radians/second)•(60 sec/1 min)= 1256.4 radians per minute
Is this correct?? Thank you and Happy New Year!
