Dos estudiantes están en un balcón que está a una altura de ℎ sobre el suelo. Cada uno de ellos lanza una pelota con una rapidez inicial de 0; uno lanza la pelota hacia arriba y el otro hacia abajo. (a) Encuentre la diferencia en los "tiempos de vuelo" de cada bola, es decir encontrar ∆t=(t2-t1). (b) Encuentre una ecuación que describa la distancia entre las bolas mientras ambas están en el aire. Responda cada pregunta en términos de 0, , ℎ, t. Sugerencia: En la pregunta (a), sería util considerar que la rapidez con que cada pelota golpea el suelo está dada por la expresión :
