A ship is going to head at quadrant bearing N50°E for 22 miles and then S70°E for 35 miles. Show a graphical model of the situation and calculate the magnitude and direction of the resultant vector.

Answer 1

in terms of the usual i-j vectors, you have
(22 cos40° + 35 cos20°)i + (22 sin40° - 35 sin20°)j = 40.74i + 2.17j
