Q. For no apparent reason, a poodle is running at a constant speed of 4.40 {rm m/s} in a circle with radius 3.0 {rm m}. Let vec v_1 be the velocity vector at time t_1, and let vec v_2 be the velocity vector at time t_2. Consider Delta vec v = vec v_2- vec v_1 and Delta t = t_2 - t_1. Recall that vec a_{rm av} = Delta vec v/ Delta t.

For Dt1 = 0.6 {rm s} compute the magnitude (to four significant figures) of the average acceleration vec a_{rm av}.
