Distancia (en metros) que recorre un proyectil disparado desde un avión de combate, se puede describir según la función: () = 8,
Stella [2.4K]

Answer:

a) La rapidez instantánea del proyectil a los 3,7 segundos de ser disparado es de 42,492 metros por segundo.

b) La aceleración instantánea del proyectil a los 4,1 segundos de ser disparado es de 17,26 metros por segundo al cuadrado.

Explanation:

El enunciado está incompleto puede prestarse a confusión, la forma correcta del mismo se presenta a continuación:

<em>La distancia en metros que recorre un proyectil disparado desde un avión de combate se puede describir según la función </em>s(t) = 8,6\cdot t + 1,25\cdot t^{2} + 0,6\cdot t^{3}<em>, donde </em>t<em> son los segundos transcurridos desde el lanzamiento del proyectil. </em><em>a)</em><em> ¿Cuál es la rapidez instantánea del proyectil a los 3,7 segundos de ser disparado? </em><em>b)</em><em> ¿Cuál es su aceleración instantánea a los 4,1 segundos de ser disparado? </em>

a) La rapidez instantánea del proyectil, en metros por segundo, es la primera derivada de la función distancia con respecto al tiempo, es decir:

v(t) = \frac{ds(t)}{dt} = 8,6 + 2,50\cdot t + 1,8\cdot t^{2} (1)

Si sabemos que t = 3,7\,s, entonces la rapidez instantánea del proyectil a los 3,7 segundos de ser disparado es:

v(3,7\,s) = 8,6 + 2,50\cdot (3,7\,s) + 1,8\cdot (3,7\,s)^{2}

v(3,7\,s) = 42,492\,\frac{m}{s}

La rapidez instantánea del proyectil a los 3,7 segundos de ser disparado es de 42,492 metros por segundo.

b) La aceleración instantánea del proyectil, en metros por segundo al cuadrado, es la segunda derivada de la función distancia con respecto al tiempo, es decir:

a(t) = \frac{dv(t)}{dt} = \frac{d^{2}s(t)}{dt^{2}} = 2,50 + 3,6\cdot t (2)

Si sabemos que t = 4,1\,s, entonces la aceleración instantánea del proyectil a los 4,1 segundos de ser disparado es:

a(4,1\,s) = 2,50 + 3,6\cdot (4,1\,s)

a(4,1\,s) = 17,26\,\frac{m}{s^{2}}

La aceleración instantánea del proyectil a los 4,1 segundos de ser disparado es de 17,26 metros por segundo al cuadrado.

Which technique does propaganda primarily use? <br> ethos <br> pathos <br> logos <br> davros
avanturin [10]

Among the options, the rhetorical device or technique primarily used by propaganda is:

B. Pathos

The three rhetorical devices as explained by Aristotle are ethos, logos, and pathos.

Ethos appeals to the speaker's authority, logos to logic or reason, and pathos to emotion.

The purpose of those devices is the convince the audience of something.

Propaganda relies primarily on pathos. It tries to evoke an emotion from the audience to convince them to do something.

Secondly, it will use ethos, appealing to authority, to what an expert says.

The last choice will be logos, and it is only used when it supports the other devices.

Think, for example, of war propaganda trying to convince people to go to war. War is not reasonable. Asking someone to die is also quite foolish.

In order to convince someone to do it, propaganda would evoke feelings of rage against the enemy, of love and protection towards one's family, etc.

With that in mind, we can choose letter B as the best option.
