Solution

Para resolver esta pregunta, primero recordemos la fórmula del momento lineal (o cantidad de movimiento) de un objeto, que es:

p=mv p = m \cdot v

donde p p es el momento, m m es la masa y v v es la velocidad.

Ahora, consideremos los cambios dados en el problema:

  • La masa del objeto se duplica, por lo que la nueva masa es 2m 2m .
  • La velocidad del objeto se reduce a la mitad, por lo que la nueva velocidad es v2 \frac{v}{2} .

Sustituyamos estos valores en la fórmula del momento:

p=(2m)(v2) p' = (2m) \cdot \left(\frac{v}{2}\right)

Simplificando la expresión:

p=2mv2=mv p' = 2m \cdot \frac{v}{2} = m \cdot v

Observamos que el nuevo momento p p' es igual al momento original p p .

Por lo tanto, la respuesta correcta es:

D. Permanece igual
