5) Dos puntos, A y B, están en la misma horizontal separados por una distancia de 500 m . Desde A parte un móvil hacia B, con una rapidez de \( 7 \mathrm{~m} / \mathrm{seg} \), y con una acelerc ción de \( 2,6 \mathrm{~m} / \mathrm{seg} \) ? . Dos segundos después y desde B, parte otro móvil hacia A con una rapidez inicial de \( 16 \mathrm{~m} / \mathrm{seg} \) y una aceleración negativa de \( 1,3 \mathrm{~m} / \mathrm{seg}^{2} \). Calcular donde y cuando se encuentran.
