4. In the small arc (radius 10 m), you enter the turn at 13 m/s, and slow down uniformly to 7 m/s over 2 seconds to the end of the turn. a. What is the magnitude of your acceleration at point W when your speed is 10 m/s? W b. Draw an arrow at (W) indicating the direction of the acceleration at that point. What is the angle between the direction of your velocity and the direction of your acceleration?

(b)Suppose the pilot makes an emergency turn to avoid an approaching missile, subjecting himself to a centripetal acceleration of 10 gs, while flying at 400 m/s (supersonic). What is the radius, in km, of his turn? (This must be short-lived because fighter planes can only briefly endure such large accelerations without serious damage, and the pilot will soon black out at 10 gs.)
