8.15m. La altura de la casa de la cual se deja caer un objeto que tarda en caer 
es de 8.15m.
La clave para resolver este problema es mediante caída libre, la velocidad inicial del objeto es 0 por lo que podemos calcular la altura h de la casa mediante la relación 
.
Conocemos la gravedad 
y el tiempo en que tarda en caer el objeto 
, sustituyendo los valores tenemos que:
