The value of the given function will be written as:-

a) f(1)= 12

b) f(n-1)= -48(\dfrac{-1}{4})^{n-1}

<h3>What is a function?</h3>

A function is defined as the expression that set up the relationship between the dependent variable and independent variable.

The given function is :-

f(n)= -48(\dfrac{-1}{4} ) ^{n}

So the value of the given function f(1) will be:-

f(1)= -48(\dfrac{-1}{4} ) ^{1}=12

The value of the function f(n-1) will be:-

f(n-1)= -48(\dfrac{-1}{4})^{n-1}

Un automóvil lleva una velocidad variable a lo largo de un trayecto de errática de modo que no podemos usar la fórmula v=d/t ni
Mademuasel [1]

Answer:

Podemos determinar la velocidad del automóvil mediante diferencias sucesivas tanto en el dominio del tiempo como en el dominio de la posición:

Dominio del tiempo

v_{i+1} = v_{i} + a_{i}\cdot \Delta t

Dominio de la posición

v_{i+1} = \sqrt{v_{i}^{2}+2\cdot a_{i}\cdot \Delta s}

Step-by-step explanation:

En este caso, es necesario tener una función que represente a esta en función del tiempo o de la posición si nos basamos en las definiciones diferenciales de aceleración (a(t)), medida en metros por segundo al cuadrado, es:

a(t) = \frac{dv}{dt} (1)

a(s) = v(t)\cdot \frac{dv}{ds} (2)

Donde:

v(t) - Velocidad del automóvil, medida en metros por segundo.

\frac{dv}{dt} - Primera derivada de la velocidad con respecto al tiempo, medida en metros por segundo.

\frac{dv}{ds} - Primera derivada de la velocidad con respecto a la posición, medida en \frac{1}{s}.

A continuación, analizamos cada ecuación:

Eq. 1

Procedemos a despejar la diferencial de velocidad e integramos la expresión resultante:

v_{f}-v_{o} = \int {a(t)} \, dt (3)

v_{f} = v_{o}+\int {a(t)} \, dt

Podemos obtener aproximaciones sucesivas al discretizar la ecuación anterior, es decir:

v_{i+1} = v_{i} + a_{i}\cdot \Delta t (3b)

Eq. 2

Procedemos a despejar la velocidad e integramos la expresión resultante:

\int {v} \, dv = \int {a(t)} \, ds (4)

\frac{1}{2}\cdot v_{f}^{2}-\frac{1}{2}\cdot v_{o}^{2} = \int {a(s)} \, ds

\frac{1}{2}\cdot v_{f}^{2} = \frac{1}{2}\cdot v_{o}^{2}+\int {a(s)} \, ds

v_{f}= \sqrt{v_{o}^{2}+2 \int {a(s)} \, ds }

Podemos obtener aproximaciones sucesivas al discretizar la ecuación anterior, es decir:

v_{i+1} = \sqrt{v_{i}^{2}+2\cdot a_{i}\cdot \Delta s} (4b)
