Si la aceleración de gravedad en la superficie de nuestro planeta es de 9,8m/s2, entonces ¿Cuál sería el peso de una persona de
andreyandreev [35.5K]

Answer:

El peso de una persona de 50 kg de masa que se encuentre sobre la superficie del planeta es 490 N.

Step-by-step explanation:

La masa es la cantidad de materia que contiene un cuerpo, mientras que el peso es la acción que ejerce la fuerza de gravedad sobre el cuerpo.

El peso se define como el producto de la masa por la aceleración de la gravedad:  

P= m*g

El peso del objeto variará de acuerdo a la fuerza de gravedad que actúa sobre este.

En el Sistema Internacional de Unidades (SI), la unidad del peso se expresa en Newton (N).

En este caso, la masa es 50 kg y la aceleración de la gravedad es 9,8 \frac{m}{s^{2} }. Reemplazando en la definición de peso:

P= 50 kg* 9,8 \frac{m}{s^{2} }

Resolviendo:

P= 490 N

<u><em>El peso de una persona de 50 kg de masa que se encuentre sobre la superficie del planeta es 490 N.</em></u>
