Answer:
The velocity of the ship relative to the earth V = 9.05
Explanation:
The local ocean current is = 1.52 m/s
Direction = 40°
Velocity component in X - direction = 1.52
°
= 1.164
Velocity component in Y - direction = 8 + 1.52
°
= 8.97
The velocity of the ship relative to the earth
Put the values of and
we get,
⇒
⇒ V = 9.05
This is the velocity of the ship relative to the earth.
