A hawk flies in a horizontal arc of radius 11.7 m at a constant speed 4.70 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 1.45 m/s2. Find the acceleration in this situation at the moment the hawk's speed is 4.70 m/s.
magnitude m/s2
direction ° from the direction of velocity towards center of the circle
