North V: 30 mph 30° 60 + 120° West в — - East South Let the blowing of wind is v= 30 mph . Solve the problem by using above direction graph. We know that in map upward represents North , dowenwards represents south and Righ hand side represents East also Left hand side represents west side.
According to Anticlockwise representation of direction the direction of wind is to from the East. Now, (1) Component of the wind towards the south will be negative of component of the wind towards the North. From the above graph - OA = VCOS 30º = 30C03 30º = 30xV2 = 1503 mps -7 - OA = -1503 mps so the component of the wind towards the south = -15/3 mps Ansuer
(2) The component of the wind towards the east will be negative of component of the wind towards the west. From the above graph - OB= Vos 600 = 30 cos60 = 30x 1 = is mps => -OB = -15 mps So the component of wind towards the east = –15 mps Anguer
