A turntable is off and is not spinning. A 0.8 g ant is on the disc and is 9 cm away from the center. The turntable is turned on and 0.8 s later it has an angular speed of 45 rpm. Assume the angular acceleration is constant and determine the quantities for the ant 0.4 s after the turntable has been turned on. Express all quantities using appropriate mks units.
