The angular speed of a propeller on a boat increases with constant acceleration from 12 rad/s to 26 rad/s in 2.5 revolutions. What is the acceleration of the propeller?

  • Physics -

    Angular acceleration = (26 - 12)/Time

    For the Time, use this equation

    (Avg. Angular speed) x time
    = 2.5*2 pi radians

    Time = 0.827 s

    Angular Acceleration
    = [14 rad/s]/0.827 s
    = ? rad/s^2
