Responder:
14,7 m / s
7,35 m / s
Explicación:
La velocidad inicial, u
Usando la relación:
v = u + en
a = - 9,8 (aceleración debido a la gravedad) hacia arriba
t = 1,5 segundos (tiempo necesario para alcanzar el máximo. Altura)
v = 0; velocidad final a máxima altura
Por eso,
0 = u - 9,8t
0 = u - 9,8 * 1,5
0 = u - 14,7
u = 14,7 m / s
Velocidad media :
Distancia recorrida / tiempo transcurrido
Distancia viajada :
v² = u² + 2aS
0 = 14,7 ^ 2 + 2 (-9,8) * S
0 = 216,09 - 19,6 S
19,6 S = 216,09
S = 216,09 / 19,6
S = 11,025
Arriba y abajo: 11.025 * 2 = 22.05
Velocidad media en todo:
S t
22.05 / 3
= 7,35 m / s
The correct answer is not A. Im sorry to say this but the correct answer is B. por la puerta de embarque (which will by by the gate). If you use the A option there would be a grammatical mistake putting the word "por" before something that makes no sense. Im a native spanish speaker and a teacher so believe the better way to say is por la puerta de embarque
4:04 1 A very good meal a o Last night we went to an Argentinian restaurant. Yes, what did you ask for? I ordered a biftec or, as they say in Argentina, "bife de lomo". How did you like it? Much. I asked for it almost raw because I know that in Argentina the steak is served well done. What did they serve you with the steak? French fries. And I ordered a side salad. It is said that in Argentina large portions are served. If true. And after eating so much we all ordered flan.

Much. And when I got home, I fell asleep right away. as they say, "with a full belly."
