![]() ![]() If we assume her head is turning about 180 degrees to look behind her, then this is happening in 180 divided by 258000/2 (average speed assuming constant acceleration) = ~0.0014 seconds. Maria’s head is therefore turning at ~4500 radians per second, or about 258 thousand degrees per second at the point of maximum angular velocity. ![]() Looking down from above, from the center of the head to the nose is about 3 inches by my estimate, or 0.0762 meters, and Mach 1 is ~343 m/s. Angular velocity w = angle theta / time t = velocity v / radius r ![]()
