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

Is this correct?

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
