A boy whirls a stone in a horizontal circle of radius 1.5 m and at height 2.0 m above level ground. The string breaks, and the stone flies off horizontally and strikes the ground after traveling a horizontal distance of 10 m.What is the magnitude of the centripetal acceleration of the stone during the circular motion?
A hawk flies at 12.0 m/s in a horizontal circle of radius 12.0 m.
Now suppose it flaps its wings harder and increases its circular speed at the rate of 1.20 m/s2 while staying in the same circular path. What is the magnitude of its acceleration, and in what direction is the acceleration vector?
