Un automóvil se mueve a velocidad constante v = 60 [km/h]. Si el tiempo de reacción del conductor al ver la luz roja de una intersección es de 0.5 [s], y ´este desacelera a razón de
40 [m/s2
] ¿Qué distancia recorre el automóvil desde el instante en que el conductor nota
la se˜nal hasta detenerse por completo? Enti´endase por tiempo de reacci´on, el intervalo
de tiempo trasncurrido entre el instante en que se percibe la se˜nal y el instante en que
se lleva a cabo la acci´on (instante en que el conductor activa el sistema de frenado).
