Un gallo se pavonea en línea recta en el techo. Su movimiento se muestra en la siguiente gráfica de la posición horizontal, x, c
Svetllana [295]

Answer:

Entonces, velocidad instantánea = | v | = 0,25 m / s

Explanation:

pregunta completa

Por favor, encontrar el archivo adjunto

Solución

La velocidad instantánea está dada por,

v = dx / dt = pendiente de la curva x-t

aquí, del gráfico:

en x = 1 m ---> t = 8 s

en x = 3 m ---> t = 0 s

entonces, dx = 1-3 = -2 m

dt = 8-0 = 8 s

Entonces,

v = -2/8

v = -0,25 m / s

Dado que, pseed es una cantidad escalar.

Entonces, velocidad instantánea = | v | = 0,25 m / s

If you dropped a rock and it fell 4.9 m in 1 s , how far would it fall in 3 s
GalinKa [24]

The formula relevant for this is:

h = v0t + 0.5 gt^2

since the rock was dropped, therefore:

h = 0.5 gt^2

 

we can see that:

h / t^2 = 0.5 g = constant

 

therefore:

4.9 m / (1 s)^2 = h / (3 s)^2

<span>h = 44.1 m </span>
