Q1. A hawk flies in a horizontal arc of radius 14 m at a constant speed of 5 m/s. (a) Find out its centripetal acceleration. (b) It continues loftly along the same horizontal arc but increases its speed at the rate of 1 m/s2. Find out the acceleration (magnitude and direction) under these conditions.
