where d8 is 4

where d8 is 4

Expert's answer

(i) The average speedis total distance over total time:

(ii) We have three displacement vectors: 40 m @ -30°, 80 m @ 0° and 60 @ 50°. Their vector sum will be

(iii) The average velocity in unit vector form from A to D:

(iv) Since we have our vector "\\vec{v}", the magnitude is

The angle will be
