Datos V = 0 D = 30 m Vf = 6m / s A = x T = x resolucion : d = (vi + vf). T 2.
Ecuaciones del movimiento uniforme variado v = v₀ + at d = v₀t + (0, 5)at² como parte del reposo entonces v₀ = 0 m / s d = 30 m v = 6 m / s entonces at = 6 (0, 5)at² = 30 at = 6 at² = 60 → (at)(t) = 60 → (6)(t) =…
Primeramente transformamos las unidades que tienen en otras para facilitar el cálculo tiempo(t) = 2min120s distancia(d) = 18km18000m te dice que parte del reposo entonces su velocidad inicial(Vo) vale 0 entonces usando…
Si es acelerado (no retardado)La distancia es d = x - xo = Vo t + 1 / 2 a t²x = posición actual, xo = posición inicial, en t = 0Saludos Herminio.
