3. A bird takes 1.8 s to change its velocity from 2.5 m/s [25°S of E] to 3.1 m/s [18°N of E]. Knowing that acceleration is a vector, describe in words the steps needed to determine the bird's average acceleration. Draw a vector diagram that would be used in the solution, but do NOT solve for the numeric value of the acceleration. (4 marks)
1. One player kicks a soccer ball 16 m [S40°W]. If a second player then kicks it 22 m [N], what is the total displacement of the ball? Include a labelled vector diagram with your trigonometric solution. (5 marks)
