An airplane is headed N 65 degrees E with an air speed of 500 miles per hour. A tail wind is blowing in the direction of N 35 degrees E at 80 miles per hour. Find the actual speed and direction of the airplane. Round off answers to one decimal.
------------------
x-vector: 500cos(65)+80cos(35) = 276.841
y-vector: 500sin(65)+80sin(35) = 499.04
-------------
resultant:
r = sqrt(276.841^2+499.04^2) = 570.685 (actual speed)
theta = tan^-1(499.04/276.841)= 60.981 degrees (actual direction)
---------------
