ME AJUDE, PFV :)

Answer 1

$S= S_{0} + V_{0} *t + \frac{a *t^{2} }{2}$

Dados: S = 700 Km; S₀ = 500 Km; t = 0,3 h; V₀ = 72 Km/h; a = ?.

$700 = 500+72*0,3+ \frac{a * 0,3^{2} }{2}$
$700=171,6 + \frac{a*0,09}{2}$
$700-171,6= \frac{a*0,09}{2}$
$2*528,4= a*0,09$
$a= \frac{1.056,8}{0,09} = 11.742,22$

A≈11.742,22
