Answer:

19.5 m

Step-by-step explanation:

EN LANZAMIENTO DE PROYECTILES, LA VELOCIDAD HORIZONTAL

PERMANECE CONSTANTE.

PRIMERO ENCUENTRA LA VELOCIDAD VERTICAL


v^(2)y = 2(
9.80 m/s^(2))(1.8 m) =
\sqrt{35.3 m^(2)/s^(2)} = 5.94 m/s

LUEGO ENCUENTRAS EL TIEMPO QUE LA FLECHA PERMANECE EN EL

AIRE.

t = 5.94 m/s /
9.80 m/s^(2) = 0.61 s

FINALMENTE ENCUENTRAS LA DISTANCIA HORIZONTAL TOTAL.

x = 32 m/s(0.61 s) = 19.5 m
