The distance that is traveled by the astronaut given that the motion is free-fall can be calculated through the equation,

    d = Vot + 0.5at²

where d is the distance, Vo is the initial velocity, t is the time, and a is the acceleration. Substituting the known,

   6 = (0 m/s)(2.7 s) + 0.5(a)(2.7 s)²

Determining the value of a,
    a = 1.646 m/s²

ANSWER: 1.646 m/s²

Si una bala de 122 g que viaja a 350 m/s golpea a un policía con chaleco antibalas el cual soporta 120 J de energía, ¿la bala at
Zanzabum

Answer:

Puesto que la energia cinética traslacional es mucho mayor que la capacidad del chaleco antibalas, la bala atravesaría el chaleco antibalas.

Explanation:

Un chaleco antibalas soporta el disparo de una bala disipando la energía de esta última a través de su propio material. Si sabemos que el chaleco antibalas soporta 120 joules de energía, cabe saber si la energía cinética traslacional es igual o inferior a ese límite, significando que la bala no atravesaría el chaleco.

La energía cinética traslacional de la bala (K), in joules, queda expresada con la siguiente fórmula:

K = \frac{1}{2}\cdot m\cdot v^{2} (1)

Donde:

m - Masa de la bala, en kilogramos.

v - Rapidez de la bala, en metros por segundo.

Si sabemos que m = 0.122\,kg y v = 350\,\frac{m}{s}, entonces la energía cinética traslacional de la bala es:

K = 7472.5\,J

Puesto que la energia cinética traslacional es mucho mayor que la capacidad del chaleco antibalas, la bala atravesaría el chaleco antibalas.
