Respuesta:
t = 4.24s
d = 294.47m
Explicación:
vf = 350km/h= 350000m/3600s = 97.2m/s
vi = 500000m/3600s = 138.9m/s
d = 500m
[tex]t = \frac{2d}{vf+vi} = \frac{2(500m)}{(97.2m/s +138.9m/s)} = \frac{1000m}{236.09m/s} = 4.24s[/tex]
[tex]d = (\frac{vf+vi}{2}).t = (\frac{0+138.9m/s}{2})(4.24s) = 69.45m/s(4.24s) = 294.47m[/tex]
