A hawk flies in a horizontal arc of radius 10.3 m at a constant speed 3.35 m/s. (a) Find its centripetal acceleration. m/s2 (b) It continues to fly along the same horizontal arc, but increases its speed at the rate of 1.15 m/s2. Find the acceleration in this situation at the moment the hawk's speed is 3.35 m/s. magnitude m/s2 direction - from the direction of velocity towards center of the circle
