Si un beisbolista lanza una pelota (ver la figura) a una velocidad inicial de 42m/s con un ángulo =70°. Averiguar:

a) La componente horizontal Vx de la velocidad en kilómetros sobre hora (km/h)

b) La componente vertical Vy de la velocidad en kilómetros sobre hora (km/h)

c) Si el ángulo cambia a un ángulo ver la figuraaveriguar la componente Vy si Vx no

cambia (es la misma del punto a)). Ayuda: Despejar h (hipotenusa) de ecuación planteada.

d) Si el ángulo cambia a un ángulo ver la figuraaveriguar la componente Vy si Vx no

cambia (es la misma del punto a)). Ayuda: Despejar h (hipotenusa) de ecuación planteada

(Ayuda: La hipotenusa del triángulo es la velocidad que lleva la pelota.)
