Fig. 1.1 shows a passenger running across a large ship at right angles to the direction in which the ship is moving.

The passenger runs across the ship at $2.4\text{ m / s}$ due north.

The large ship is travelling due east at $6.8\text{ m / s}$.

Determine, either graphically or by calculation, the resultant velocity of the passenger. Give the direction in which the passenger is moving relative to due north.

Show how the answer is obtained.

velocity = ______ $\text{m / s}$ at ______ $^\circ$ from due north
