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. (5 pts) b) What was the average acceleration of the plane over this time interval? (1 pt) c) Explain why the speed of the plane changed and yet the plane accelerated.(1 pt) Please labeled sketches with events as well as GRASS and explanations to show your work. Please label the triangle sides. Remember to have the magnitude rounded to a reasonable number of sig figs, the unit and the direction (if needed) in your answers. 9. In a total time of 2.0 min, a duck on a pond paddles 22 m [E36'N] and then paddles another 65 m [525*E]. Solve for the displacement graphically and then answer the questions. The scale diagram should have a scale, labelled axes, correct vector length and directions, vector labels, appropriate significant digits based on your measuring device and a final answer with magnitude to correct sig figs, with unit and direction. (6 pts) Also, calculate the duck's average velocity, the distance travelled, and the average speed. ( 3 pts)
