Explanation:
Las condiciones del problema requieren el cálculo de la rapidez inicial de los guijarros. Se sabe que el componente vertical de la rapidez final es cero. Por tanto, el tiempo se determina a continuación: (The conditions of this problems require the calculation of the initial speed of the peebles. It is known that vertical component of the final speed is zero. Therefore, the time is determined herein:).
Además, se determina el componente horizontal de la rapidez inicial (Likewise, the horizontal component of the initial speed is determined):
El guijarro tiene una rapidez de
cuando golpea la ventana (The peeble has a speed of 
when it hits the window).
