A girl delivering newspapers covers her route by traveling 2.00 blocks west, 5.00 blocks north, and then 8.00 blocks east.
(a) What is her resultant displacement?
(only enter the angle of the resultant in the answer space below, not the distance)
enter it as a positive angle, between 0-360 degrees
a. D = -2 + 5i + 8 = 6 + 5i.
D2 = 6^2 + 5^2 = 61
D = 7.81 Blocks.
b. ta A = Y/X = 5/6 = 0.83333
A = 39.8o
