Buenos días;
1) La ecuación de la velocidad en un movimiento uniformemente acelerado (M.U.A) es:
V=V₀+at.
V=30 m/s-2 m/s².t
Ahora elimina las unidades (m/s, m/s₂), y tendrás la ecuación de la velocidad en función del tiempo.
V(t)=30-2t.
Sol: la ecuación de la velocidad en función del tiempo es : V(t)=30-2t.
2) La ecuación de la posición en función del tiempo en un M.U.A es:
X=X₀+V₀.t+(1/2).a.t²
X=0+30 m/s.t+(1/2).(-2 m/s²).t²
Eliminas las unidades, y tendrás la ecuación de la posición en función del tiempo.
X(t)=30.t-t².
Sol: la ecuación de la posición en función del tiempo es: X(t):30t-t²
Un saludo.
