9. The ( x,y ) coordinates (in meters) of the points are A = (15, 15), B = (30, 45), C = (20, 15), and D = (45, 45). The respective times are t A = 0, t B = 300 s, t C = 600 s, and t D = 900 s. Average velocity is defined by Eq. 4-8. Each displacement Δ r is understood to originate at point A . (a) The average velocity having the least magnitude (5.0 m/600 s) is for the displacement ending at point C : | | 0.0083 m/s. avg v = G (b) The direction of

Unformatted text preview: avg v G is 0 ° (measured counterclockwise from the + x axis). (c) The average velocity having the greatest magnitude ( 2 2 (15 m) (30 m) /300 s + ) is for the displacement ending at point B : | | 0.11 m/s. avg v = G (d) The direction of avg v G is 297 ° (counterclockwise from + x ) or − 63 ° (which is equivalent to measuring 63 ° clockwise from the + x axis)....
