Unos niños juegan en el patio de la escuela, y accidentalmente el balón sale al exterior por encima de la valla del campo. Un hombre que bien pudo haberse llevado el balón, le da una patada al balón para devolverlo al interior. Sabiendo que el muro del patio tiene 5 m de altura, que el hombre está a 50 m del muro y que patea el balón a 24 m/s con un ángulo de 55°, averiguar si consigue que la pelota vuelva a entrar al patio o, por el contrario pasa sobre el muro. Si no lo consiguió, que distancia, con que ángulo y que velocidad debe patear el balón.
