A hawk flies in a horizontal arc of radius 12.0 m at a constant speed of 7.1 m/s. It continues to fly along the same horizontal arc but increases its speed at the rate of 7.9 m/s2. Find the acceleration magnitude under these conditions.

radial A = v^2/r
tangential A = 7.9
they are perpendicular
|A| = sqrt ( v^4/r^2 + 7.9^2 )
tangential A = 7.9
they are perpendicular
|A| = sqrt ( v^4/r^2 + 7.9^2 )
