Unformatted text preview: what is the radius of the circle? What is the centripetal acceleration of the airplane? (Useful info: the circumference of a circle is 2 times the radius.) Solution: First, find the angular velocity: = 2 / 120 s = 5.24 x 10-2 rad/s From this, find the radius: r = v/ = 200/5.24 x 10-2 = 3820 m The centripetal acceleration is: a c = v 2 /r = 10.5 m/s 2...
