Question

A point on the rim of a wheel moves with speed of 200 feet per second. Find the angular velocity of the point if the diameter of the wheel is 8 feet.

Answer 1

The angular velocity of the point is found this way:

w = v/r

w = 200/(8/2) <--the two is from 2 * Pi * r

w = 50 rad/sec.

Answer: 50 rad/sec.
