[tex]600m[/tex]
Explicación:
Datos:
[tex]Velocidad-inicial: V_{0} = 60m/s[/tex]
[tex]Velocidad-final: V_{f} =40m/s[/tex]
[tex]Tiempo: t = 6s[/tex]
[tex]Espacio-recorrido: d = ?[/tex]
Fórmula:
[tex]V_{f} =V_{0} -at,despejamos"a".[/tex]
[tex]a = \frac{V_{0}-V_{f} }{t} = \frac{60m/s -40m/s}{6s} = \frac{20m/s}{6s } = 3.333m/s^{2}[/tex]
[tex]V_{f} ^{2} = V^{2} _{0} } -2ad, despejamos"d".[/tex]
[tex]d = \frac{V^{2} _{0} -V^{2} _{f} }{a} =\frac{(60m/s)^{2}-(40m/s)^{2} }{3.333m/s^{2} } = \frac{3600m^{2}/s^{2}-1600m^{2} /s^{2} }{3.333m/s^{2} } = \frac{2000m^{2}/s^{2} }{3.333m/s^{2} } = 600 m[/tex]
[tex]d = 600m[/tex]
