Una persona A tiene cierta cantidad de masa y una persona B tiene la mitad de masa de la persona A ¿como es el peso de B respect
musickatia [10]

Answer:

El peso de la persona B es la mitad del peso de la persona A.

Explanation:

El peso de la persona B puede calcularse con la siguiente ecuación:

P_{B} = m_{B}g   (1)

En donde:

m_{B}: es la masa de la persona B

g: es la gravedad

Dado que la persona B tiene la mitad de la masa de la persona A, tenemos:

m_{B} = \frac{m_{A}}{2}  (2)

En donde:

m_{A}: es la masa de la persona A

Al introducir la ecuación (2) en (1) nos queda:

P_{B} = \frac{m_{A}}{2}g   (3)

Sabemos que el peso de la persona A está dado por:

P_{A} = m_{A}g   (4)

Entonces, al introducir la ecuación (4) en (3) tenemos:

P_{B} = \frac{P_{A}}{2}

Por lo tanto, el peso de la persona B es la mitad del peso de la persona A.
