Circular Motion Question!! 1. The problem statement, all variables and given/known data A hawk flies in a horizontal arc of radius 18.3 m at a constant speed of 2.3 m/s. It continues to fly along the same horizontal arc but increases its speed at the rate of 1.56 m/s2. Find the magnitude of acceleration under these new conditions. Answer in units of m/s2. 2. Relevant equations A=V^2/r 3. The attempt at a solution The Centripital Acceleration is .29m/s2, and I stumped. Any help?
