1. Electric toothbrushes can be effective in removing dental plaque. One model consists of a head 1.1 cm in diameter that rotates back and forth through a 70.0 angle 7600 times per minute. The rim of the head contains a thin row of bristles. (See the figure )Assuming that the toothbrush has constant angular acceleration in each of the directions it turns, find the angular acceleration (in rad/sec2 ) of the rotating head and the tangential acceleration (in m/s2 ) of the bristles.
What is the rotational acceleration in rad/sec2
What is tangental accelration in m/s2
What is the rotational acceleration in rad/sec2
What is tangental accelration in m/s2
