What is the angular velocity of a point in a rotating CD that has a linear velocity of 2cm/s and a radius of 0.5cm and is this angular velocity the same for every point in the CD?

A wheel with a radius of 10 meters starts from rest when it is given an angular acceleration of 11 rad/s2.  Answer the following for the time 12 seconds after the acceleration begins. (Round ALL of the following answers to the nearest whole number) The magnitude of the wheel's angular velocity is ___________ rad/s.  The magnitude of the tangential acceleration for a point on the edge of the wheel is ___________ m/s2. The magnitude of the centripetal acceleration for a point on the edge of the wheel is _________ m/s2.

(a) If this bicycle wheel depicted makes 360 revolutions in 4 minutes and 48 seconds at constant speed, what was the average angular velocity of the wheel in units of radians per second?   (b)   If the diameter of the wheel is 27.5 inches, then what distance (arc length) in meters has the red spot on the very outer periphery of the wheel travelled in 360 revolutions? (in meters)   (c)   How many meters has the red spot travelled in just one revolution?   (d)   What is the Period of Rotation, T, (in units of seconds), of the red spot?   (e)   What is the tangential velocity of the red spot? (in units of meters per second)?   (f)   The wheel is attached to a mountain bike that accelerates from a tangential linear speed of 4.47 m/s to 7.77 m/s in 21.8 seconds. What was the angular acceleration of the wheel during this acceleration period in units of rad/sec^2 ?
