An ant walks on a piece of graph paper straight along the x axis a distance of 10.0 cm in 2.00 s. It then turns left 30.0 degrees and walks in a straight line another 10.0 cm in 1.90 s. Finally, it turns another 70.0 degrees to the left and walks another 10.0 cm in 1.40 s.
A. Determine the x component of the ant's average velocity.
B. Determine the y component of the ant's average velocity.
C. Determine the magnitude of ant's average velocity.
D. Determine the direction of ant's average velocity.

A. Divide the total change in the x coordinate by (2.0+1.9+1.4 =) 5.3 s
B. Divide the total change in the y coordinate by 5.3 s.
C. Use the Pythagorean Theorem with the previous two results
D. arctan (B answer)/(A answer)
counterclockwise from +x
