Respuesta:
[tex]Vo = -2.05m/s[/tex]
[tex]Vf = 24.97 m/s[/tex]
Explicación:
primero calculamos la velocidad inicial
[tex]d = Vo.t+\frac{a.t^{2} }{2}[/tex]
[tex]103 = Vo.9+\frac{3 . 9^{2} }{2}[/tex]
[tex]103 = Vo.9+\frac{3 . 81 }{2}[/tex]
[tex]103 = Vo.9+\frac{243}{2}[/tex]
[tex]103 = Vo.9+ 121.5[/tex]
[tex]-121.5 + 103 = Vo9[/tex]
[tex]-18.5 = Vo9[/tex]
[tex]Vo = -18.5/9[/tex]
calculamos la velocidad final
[tex]Vf = Vo+a.t[/tex]
[tex]Vf = -2.05+3.9[/tex]
[tex]Vf = -2.05+27[/tex]
