Question
if the 78.0 kg astronaut were in a spacecraft 6r from the center of the earth, what would the astronauts weight be on earth? in the spacecraft? 760 n 764.4 n 764 n
Step1: Definir la fórmula del peso en la superficie de la Tierra
El peso de un objeto en la superficie de la Tierra se calcula como $W = mg$, donde $m$ es la masa del objeto y $g$ es la aceleración gravitacional en la superficie de la Tierra ($g\approx9.8\ m/s^{2}$). Dado que $m = 78.0\ kg$, entonces $W=78.0\times9.8$.
Step2: Realizar el cálculo
$W = 78.0\times9.8=764.4\ N$
