SUMMARY
The discussion focuses on calculating centripetal acceleration for a hawk flying in a horizontal arc with a radius of 10.7 meters at a constant speed of 3.75 m/s, yielding a centripetal acceleration of 1.31 m/s² using the formula Ac = v² / r. In the second part, the hawk accelerates at a rate of 1.30 m/s² while maintaining its circular path, requiring the combination of centripetal and tangential acceleration to determine the resultant acceleration vector. The confusion arises from the distinction between centripetal acceleration and total acceleration when speed increases.
