10. A plane flying at 245 m/s [E270S] takes 36 seconds to change its velocity to 245 m/s [S270E]. a) Solve for the change in velocity of the plane algebraically. b) What was the average acceleration of the plane over this time interval? c) Explain why the speed of the plane changed and yet the plane accelerated.
