Homework Answers
a)
u = - 5 and v = 0
speed = sqrt(u2 + v2)
speed = sqrt((-5)2 + (0)2) = 5 knots
direction : tan-1(v/u) = tan-1(0/(-5)) = 180 deg from positive x-axis or east direction .
b)
u = 8 and v = - 2
speed = sqrt(u2 + v2)
speed = sqrt((8)2 + (- 2)2) = 8.25 m/s
direction : tan-1(v/u) = tan-1(-2/8) = - 14.04 deg
14.04 deg south of east
c)
u = - 1 and v = 15
speed = sqrt(u2 + v2)
speed = sqrt((- 1)2 + (15)2) = 15.03 mi/h
direction : tan-1(v/u) = tan-1(15/(-1)) = 93.8 deg counterclockwise from positive x-axis or east direction .
d)
u = 6 and v = 6
speed = sqrt(u2 + v2)
speed = sqrt((6)2 + (6)2) = 8.5 knots
direction : tan-1(v/u) = tan-1(6/6) = 45 deg counterclockwise from positive x-axis or east direction .
