2. Calculate the angular speed of the 26-inch bicycle rotating at 200 revolutions per minute. Express your answer in radians per
minute. Use π = 3.14. My answer:
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
The angular velocity for this problem is given by: Angular speed = 200 rev / min The first thing you should keep in mind is the following conversion: 1 rev = 2π radians Applying the conversion we have: Angular speed = 200 * (2π) Rewriting: Angular speed = 200 * (2 * 3.14) Angular speed = 1256 radians / minutes Answer: the angular speed is: Angular speed = 1256 radians / minutes
