A Plane has an airspeed of $500 \mathrm{kmph}$ due north. A Wind blows at $100 \mathrm{km}/\mathrm{h}$ from east to west. Draw a vector diagram to calculate the resultant velocity of the plan Give The direction of travel of the plane with respect to north.

A Plane has an airspeed of $500 \mathrm{kmph}$ due north. A Wind blows at $100 \mathrm{km}/\mathrm{h}$ from east to west. Draw a vector diagram to

The plane lies for $15 \min$. Calculate the displacement of the plane in this time.

A small aircraft for one is used for a short horizontal flight. On its journey from  $\mathrm{A} \mathrm{to} \mathrm{B}$, the resultant velocity is $15 {\mathrm{ms}}^{-1}$in a direction ${60}^{°}$ east of north and the wind velocity is $7.5 {\mathrm{ms}}^{-1}$due north. Show that for the aircraft to travel from $\mathrm{A} \mathrm{to} \mathrm{B}$ it should point due east.

After flying $5 \mathrm{km}$from $\mathrm{A} \mathrm{to} \mathrm{B}$, the aircraft return along the same path from $\mathrm{B} \mathrm{to} \mathrm{A}$ with a resultant velocity of $13.5 {\mathrm{ms}}^{-1}$ assuming that the time spent at $\mathrm{B}$ is negligible, calculate the average speed for the complete journey from $\mathrm{A} \mathrm{to} \mathrm{B}$ and back to $\mathrm{A}$.
