Respuesta:
Datos:
Velocidad inicial(Vi) = 32 m/s
Velocidad final(Vf) = ?
Gravedad(g) = 9.807 m/s²
Altura(h) = ?
Tiempo(t) = 3 s
Formulas:
h = (Vi)(t) + 1/2(g)(t)²
Vf = Vi + gt
Procedimiento:
1.- Calcular la altura
h = (32 m/s)(3 s) + 1/2(9.807 m/s²)(3 s)²
h = 96 m + 1/2(9.807 m/s²)(9 s²)
h = 96 m + 88.263/2 m
h = 96 m + 44.1315 m
h = 140.1315
2.- Calcular la velocidad final
Vf = 32 m/s + (9.807 m/s²)(3 s)
Vf = 32 m/s + 29.421m/s
Vf = 61.421 m/s
