Answer:

The aircraft is gaining altitude at 250\frac{mi}{h}

Explanation:

Draw a vector diagram. (Right angle triangle speed as the hypotenuse)

Let

x -----> horizontal component of the speed

y ----> vertical component of the speed

s ----> speed in miles per hour

we know that

x=cos(30\°)(s)

y=sin(30\°)(s)

we have

s=500\ \frac{mi}{h}

cos(30\°)=\frac{\sqrt{3}}{2}

sin(30\°)=\frac{1}{2}

substitute

x=\frac{\sqrt{3}}{2}(500)

x=250\sqrt{3}\frac{mi}{h}

y=\frac{1}{2}(500)

y=250\frac{mi}{h}

therefore

The aircraft is gaining altitude at 250\frac{mi}{h}
