1. Se dispara una bala de 10grbcon una velocidad de 500m/s contra un muro de 10cm de espesor. Si la resistencia del muro al avan
vodomira [7]

Answer:

1) La velocidad de la bala después de atravesar el muro es de aproximadamente 435,890 metros por segundo.

2) La potencia del automóvil es 96438,272 watts o 131,208 caballos de vapor.

3) La velocidad del objeto al llegar al suelo es aproximadamente 14,005 metros por segundo.

Step-by-step explanation:

1) La velocidad final de la bala puede determinarse mediante el Teorema del Trabajo y la Energía, a partir del cual se tiene la siguiente fórmula:

\frac{1}{2}\cdot m\cdot v_{o}^{2} -F\cdot \Delta s = \frac{1}{2}\cdot m \cdot v_{f}^{2} (1)

Where:

m - Masa de la bala, en kilogramos.

v_{o}, v_{f} - Velocidades inicial y final de la bala, en metros por segundo.

F - Resistencia del muro al avance de la bala, en newtons.

\Delta s - Espesor del muro, en metros.

Si sabemos que m = 0,01\,kg, v_{o} = 500\,\frac{m}{s}, F = 3000\,N and \Delta s = 0,1\,m, entonces la velocidad final de la bala es:

v_{f}^{2}=v_{o}^{2} -\frac{2\cdot F\cdot \Delta s}{m}

v_{f} = \sqrt{v_{o}^{2}-\frac{2\cdot F\cdot \Delta s}{m} }

v_{f} \approx 435,890\,\frac{m}{s}

La velocidad de la bala después de atravesar el muro es de aproximadamente 435,890 metros por segundo.

2) Asumamos que el automóvil acelera a tasa constante, significando que la fuerza neta será constante. Para un sistema cuya fuerza neta sea constante, la potencia experimentada queda descrita por la siguiente ecuación:

P = m\cdot a(t)\cdot v(t) (2)

a(t) = a (3)

v(t) = v_{o} + a\cdot t (4)

Donde:

P - Potencia, en watts.

m - Masa del automóvil, en kilogramos.

a(t) - Aceleración, en metros por segundo al cuadrado.

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

v_{o} - Velocidad inicial del automóvil, en metros por segundo.

Si sabemos que m = 1000\,kg, a = 3,472\,\frac{m}{s}, v_{o} = 0\,\frac{m}{s} y t = 8\,s entonces la potencia experimentada por el automóvil es:

P = 96438,272\,W (131,208\,C.V.)

La potencia del automóvil es 96438,272 watts o 131,208 caballos de vapor.

3) El cuerpo experimenta un Movimiento de Caída Libre, el cual es un Movimiento Uniformemente Acelerado debido a la gravedad terrestre. La velocidad del cuerpo al llegar al suelo se determina mediante la siguiente fórmula cinemática:

v_{f} = \sqrt{v_{o}^{2}+2\cdot g\cdot h} (5)

Donde:

v_{o} - Velocidad inicial del cuerpo, en metros por segundo.

v_{f} - Velocidad final del cuerpo, en metros por segundo.

g - Aceleración gravitacional, en metros por segundo al cuadrado.

h - Altura recorrida por el cuerpo, en metros.

Si sabemos que v_{o} = 0\,\frac{m}{s}, g = 9,807\,\frac{m}{s^{2}} y h = 10\,m, entonces la velocidad al llegar al suelo es:

v_{f} \approx 14,005\,\frac{m}{s}

La velocidad del objeto al llegar al suelo es aproximadamente 14,005 metros por segundo.

ASHA 777 [7]

Answer:

(Choice A)

Juanita gets a strike next game.'

Step-by-step explanation:

Your question is obviously incomplete.

Complete question is:

Juanita and Nina are bowling together. The probability of Juanita getting a strike next game is 24%. The probability of Nina getting a strike next game is 0.17. Which of these events is more likely?

(Choice A)

Juanita gets a strike next game.'

(Choice B)

Nina gets a strike next game.

(Choice C)

Neither. Both events are equally likely.

Answer:

Probability of Juanita : P(J)= 24% => 0.24

probability of Nina getting a strike next game: P(N) = 0.17

As you can see 0.24 > 0.17 ----> P(J)>P(N)

Thus it can be concluded that Juanita gets a strike next game is more likely.

so, choice A

Let f(x) = 5x – 3 and g(x) = 2x². Perform the function operation and then find the domain of the result.
MAXImum [283]

Answer:

(f+g)x= 2x²+5x-3

The domain x∈ Real number.

Step-by-step explanation:

Given that f(x) = 5x - 3 and g(x) = 2x²

(f+g)x = f(x) + g(x)

So, by using the given function

(f+g)x= (5x-3) + (2x²)= 2x²+5x-3

As the result, 2x²+5x-3, is a polynomial, so domain of the result is all the real numbers.
