10.2 Chapter 10 D EVELOP Given a constant angular acceleration α , the angular velocity and angular position at a later time t can be found using Equations 10.7 and 10.8: ω ω α θ θ ω α = + = + + 0 0 0 2 1 2 t t t E VALUATE (a) The initial and final angular velocities are ω 0 0 = and ω π = = = = 3600 1 2 3600 60 377 rpm 3600 rev min rad s ( ) rad/s Therefore, the amount of time it takes to reach this angular speed is t = = = = ω ω α 0 377 0 0 52 725 12 1 rad/s rad/s s min 2 .
