A girl delivering newspapers travels 2 blocks
west, 10 blocks north, then 4 blocks east.
What is the magnitude of her resultant dis-
placement?
077 (part 2 of 3) 10.0 points
Find the direction (measured from due east,
with counterclockwise positive) of her dis-
placement.

• physics -

X = hor = 4 - 2 = 2 Blocks.

Y = ver. = 10 Blocks.

tanA = Y/X = 10 / 2 = 5,
A = 78.7 deg.

R = X/cosA = 2 /78.7 = 10.2 Blocks @
78.7Deg.
