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 $250\frac{mi}{h}$

C. 50 years

D. The population will decrease

E. Unusually low rate of natural increase and total fertility

Explanation:

A. The two types of data in the table that are used to calculate the rate of natural increase are The Birth rate (per 1,000 population) and the birth rate (per 1,000 population)

B. The total fertility rate is the number of children expected per woman during her childbearing years

C. The doubling time is given by T = 70/(1.4) = 50 years

D. To maintain the current population size, a fertility rate of 2.1% is required, whereby the fertility rate is about 1.8% the population will not be stable or would decrease

E. The population statistic with a total fertility rate below 1.8, a low rate of natural increase, and a low birth rate is not inline with other industrializing economies such as Middle East, with a fertility rate of 3.0.
