At a particular instant in time, a train is traveling north at 5 m/s and decelerating at a rate of 0.5 m/s2 as it enters a right turn (eastward) with a radius of curvature of 100 m. at the front of the train a record player is spinning a record on a horizontal surface at a rate of 6 rad/s counter-clockwise with an angular deceleration of 0.5 rad/s2. on top of the spinning record, an ant is walking directly toward the center with a velocity of 0.1 m/s and an acceleration of 0.01 m/s2. at the same instant that the train enters the eastward curve, the ant is 0.2m from the center of the record and is located directly to the east of the center, such that he is walking due west. what is the magnitude of the ant's total acceleration relative to the ground?
