A turntable is off and is not spinning. A 1.5 g ant is on the disc and is 18 cm away from the center. The turntable is turned on and 1.4 s later it has an angular speed of 33 rpm. Assume the angular acceleration is constant and determine the following quantities for the ant 0.7 s after the turntable has been turned on. Express all quantities using appropriate mks units.

A peanut sits 8.0 cm away from the center of a turntable that is spinning at a rate of 200 rad/s. If it takes 15.0 s from the turntable to come to a stop at a constant rate, what is the direction relative to the vertical of the force exerted on the peanut by the turntable 14.7 s after the turntable has begun slowing down? With a diagram if possible.
