Answer to Question #143420 in Classical Mechanics for Isurini Sirisena

Question

4. A plane is flying at 240 m s−1, on a bearing of 125º from due
north. Calculate its velocity component due south, and its
velocity component due east.

Answer 1

Answer

Velocity (v) =240m/s

Angle$(\theta) =125-90=35°$

Components in East =$vcos\theta\\$

$240\times cos35°=196.5m/s$

Component in South

$=vsin\theta=240\times sin35°\\=137.6m/s$
