The shaft of a vacuum cleaner motor rotates with an angular acceleration of four times the shaft’s angular velocity raised to the ¾ power. the vacuum beater bar is attached to the motor shaft with pulley through a drive belt. the radii of the motor pulley and the beater bar are 0.25 in and 1.0 in respectively. determine the angular velocity of the beater bar when t = 4 s, given that omega_0 is 1 rad/s when theta = 0.
