Return to polar form
Magnitude = sqrt(603.923^2 60^2) = 606.9
Direction = arctan(60 / 603.923) = 5.67 degrees north of east
Decompose each vector into x-y
500 km/h due east = (500, 0)
120 km/h at 30 deg. north of east
= (120 cos(30), 120 * sin(30))
= (120 * sqrt(3) / 2, 120 * 1 / 2)
= (60 * sqrt(3), 60)
Add the vectors.
(500, 0) (60 * sqrt(3), 60)
= (500 60 * sqrt(3), 60)
= (603.923, 60)
Magnitude = sqrt(603.923^2 60^2) = 606.9
Direction = arctan(60 / 603.923) = 5.67 degrees north of east
Magnitude = sqrt(603.923^2 60^2) = 606.9
Direction = arctan(60 / 603.923) = 5.67 degrees north of east
