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
