Question
At what point on a collection of ramps does a motionless wagon have the most energy?At the bottom of the longest rampAt the top of the longest rampAt the bottom of the tallest rampAt the top of the tallest ramp
Solution
Para determinar en qué punto un vagón inmóvil tiene más energía en una colección de rampas, debemos considerar la energía potencial gravitatoria, que depende de la altura del vagón respecto al suelo. La fórmula para la energía potencial gravitatoria es:
donde:
- es la energía potencial,
- es la masa del vagón,
- es la aceleración debida a la gravedad,
- es la altura.
Siguiendo estos pasos:
-
Identificar la variable clave: La energía potencial depende directamente de la altura ().
-
Comparar las opciones:
- En la parte inferior de la rampa más larga, la altura es mínima o cero.
- En la parte superior de la rampa más larga, la altura es mayor que en la parte inferior, pero no necesariamente la mayor.
- En la parte inferior de la rampa más alta, la altura es mínima o cero.
- En la parte superior de la rampa más alta, la altura es máxima.
-
Conclusión: La energía potencial es mayor cuando la altura es mayor. Por lo tanto, el vagón inmóvil tiene más energía en la parte superior de la rampa más alta.
La respuesta correcta es: En la parte superior de la rampa más alta.
