Chuck Norris’s roundhouse kick is quite impressive. Suppose his foot begins from rest and takes two thirds of a second to swing totally around a 1.10-m circular arc. (a) If the angular acceleration is assumed constant for the first third of a second, and then zero after that, what is its magnitude? (b) What is the foot’s tangential acceleration through the first 0.33 s? What is (c) the maximum tangential speed his foot obtains and (d) at what percent of a full rotation does this occur?
