Desde que altura debe caer un objeto para que impacte con el suelo con una velocidad de 35 m/s

Answers

Answer 1

Answer:

height: 61.25 metros

Explanation:

velocity:

[tex]v=\sqrt{2gh}[/tex]

[tex]35=\sqrt{(2)(10)h}[/tex]

[tex]35=\sqrt{20h}[/tex]

[tex](35)^{2} =(\sqrt{20h} )^{2}[/tex]

[tex]1225=20h[/tex]

[tex]\frac{1225}{20} =h[/tex]

[tex]h=61.25[/tex]

Hope this helps

Answer 2

El objeto debe caer desde una altura de 62.455 metros para impactar el suelo con una velocidad de 35 metros por segundo.

Determinación de la altura inicial de un móvil bajo movimiento de caída libre

La caída libre es un movimiento uniformemente acelerado debido únicamente a la gravitación terrestre, en donde se desprecia los efectos de la viscosidad del aire, la rotación de la Tierra y la distancia con respecto al planeta.

Para determinar la altura inicial ([tex]y[/tex]), en metros, debemos emplear la siguiente fórmula cinemática si asumimos la altura final como cero y es lanzado desde el reposo:

[tex]y = \frac{v^{2}}{2\cdot g}[/tex]     (1)

Donde:

[tex]g[/tex] - Aceleración gravitacional, en metros por segundo al cuadrado.[tex]v[/tex] - Velocidad final, en metros por segundo.

Si conocemos que [tex]g = 9.807\,\frac{m}{s^{2}}[/tex] y [tex]v = 35\,\frac{m}{s}[/tex], entonces tenemos que la altura inicial es:

[tex]y = \frac{35^{2}}{2\cdot (9.807)}[/tex]

[tex]y = 62.455\,m[/tex]

El objeto debe caer desde una altura de 62.455 metros para impactar el suelo con una velocidad de 35 metros por segundo. [tex]\blacksquare[/tex]
