An aircraft is climbing at a 30 degree angle to the horizontal. How fast is the aircraft gaining altitude if it's speed is 500 m

denis-greek [22]

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 $250\frac{mi}{h}$

1. Poor communication: Communication is vital in every relationship. The way people communicate in their relationship has either a negative or positive effect on the relationship. One of the main contributor to a detrimental relationship is poor communication.

When there's a communication breakdown, this will result into argument, low self esteem, hatred for each other etc.

2. Dishonesty: In every relationship, honesty is paramount. One should be honest in their relationships. Dishonesty brings about lack of trust and this is bad for the relationship. It's important to be transparent. Don't keep secrets from each other.
