segundo cuerpo, se tira hacia abajo con una
velocidad inicial de 100 cm/s.
a) Cuánto será la distancia entre ellos de 18
m?.
b) Cuál es la distancia recorrida a partir del
punto delanzamiento?
10. Un cuerpo se mueve con movimiento
rectilíneo desacelerado, viaja 77 m en 2 seg.

aceleración, encuanto tiempo se detiene?
11. Un proyectil es disparado con una velocidad
de 600 m/seg haciendo un ángulo de 60º con
la horizontal. Calcular:
a. El alcance horizontal.
b. La altura máxima.
c. Lavelocidad y la altura después de 30
seg.
12. Un cuerpo, inicialmente en reposo ( y
