2. Um avião levanta voo de um solo segundo ângulo igual a 30º. Com uma velocidade de 100m/s em 1 minuto a altura máxima atingida pelo avião foi igual a:

Respuesta :

Answer:

height = 3000m

Step-by-step explanation:

In order to calculate the height reached by the airplane, you first calculate the distance traveled by the airplane in one minute. The distance is given by:

[tex]d=vt[/tex]    (1)

v: speed of the airplane = 100m/s

t: time = 1 min = 60 s

you replace in the equation (1):

[tex]d=(100m/s)(60s)=6000m[/tex]

The distance traveled by the airplane while it is going up, can be considered as a hypotenuse of a rectangle triangle.

The angle at which the airplane started to fly was 30°. Then, you can use the following trigonometric relation to calculate the height:

[tex]sin(30\°)=\frac{height}{d}\\\\height=dsin(30\°)=(6000m)sin(30\°)=3000m[/tex]

hence, the height reached by the ariplane is 3000m
