A hawk flies in a horizontal arc of radius 11.7 m at a constant speed 3.90 m/s.
(a) Find its centripetal acceleration.
1Your answer is correct. m/s2
(b) It continues to fly along the same horizontal arc, but increases its speed at the rate of 1.40 m/s2. Find the acceleration in this situation at the moment the hawk's speed is 3.90 m/s.magnitude 2Your answer was incorrect, but has changed from what was graded. Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. m/s2 direction 3° from the direction of velocity towards center of the circle
