This problem applies concepts of uniform circular motion to a situation many of us have experienced: Being in an airplane as it makes a series of turns to get ready for landing. Airplanes in the landing pattern typically make what are called "standard turns" in which the airplane's heading (the angle between the direction it is pointed and north) changes by 3 degrees per second. At that turn rate, it takes 120 seconds (360 degrees divided by 3 degrees per second) to make a complete circle. Part A If an airplane is making a standard turn at a speed of 80 m/s (about 180 mph), what is the radius of the turn? > View Available Hint(s) AEd m Submit Part B At the speed and turn rate given above, what is the airplane's centripetal acceleration?
