Question

An aeroplane travels 200 km on a straight course making an angle 300 east
of due north. How far north and how far east does the plane travel from its starting point?
​

Answer 1

Answer:

Net displacement towards East is 150 km and towards north it is 260 km

Explanation:

Net displacement of the plane is 200 km at 30 degree East of North

So we have

$d = 300 km$@ 30 degree East of North

now we have

$d_x = 300 sin30$ toward East

$d_x = 150 km$ East

Similarly we have

$d_y = 300 cos30$ Towards North

$d_y = 150\sqrt3 km$ Towards North
