A ship moves along equator to the east with velocity 30km/hr. The south-eastern wind blows at an angle of 60° to equator with velocity 15 km/hr. Find the wind velocity relative to ship and angle between the equator and the wind direction in reference frame fixed to the ship.

Velocity of the ship = 30 km/hr

Velocity of south-eastern wind = 15 km/hr

The velocity of wind relative to ship is given by,

Here, we have

Now the magnitude of relative velocity of wind relative to ship is,
