    A flywheel whose diameter D= 1.2 m, is initially rotating at Wo= 200 revolutions per minute. During time t- 60 sec, its rotation rate increases with constant acceleration to a final value of Wf= 1000 rev/min.
    Part a. find the initial tangential speed in m/sec, of a point on the rim.
    Part b. find the angular acceleration in radians per second squared.
    Part c. find the total number of radians it rotates during the 60 seconds.

    Part a.
    Step 1. From angular motion description equations, recall that the relation between angular velocity W of an object and the linear, tangential speed along a circle of radius R, is given by:
    (1) Vtan = R W
    Step 2. Substituting given values with units, and converting min to sec should ...

    Solution Summary
