A ship moves along the equator to the east with velocity `v_0=30km//hour`. The southeastern wind blows at an angle `varphi=60^@` to the equator with velocity `v=15km//hour`. Find the wind velocity `v^'` relative to the ship and the angle of `varphi^'` between the equator and the wind direction in the reference frame fixed to the ship.
