Question

me ajudem nesta ,preciso da resposta ate as 2:15 , obrigado !

Answer 1

$\boxed{S=So+Vo*t+ \frac{a*t^2}{2}}$
$\boxed{S=0+10*30+ \frac{a*30^2}{2}}$
$\boxed{S=10*30+ \frac{a*900}{2}}$
$\boxed{S=300+450*a}$

$V=Vo+at$
$30=10+30a$
$30-10+30a$
$30a=20$
$3a=2$
$\boxed{a= \frac{2}{3}}$

$\boxed{S=300+450*a}$
$\boxed{S=300+450*\frac{2}{3}}$
$\boxed{S=300+\frac{900}{3}}$
$\boxed{S=300+300}$
$\boxed{\boxed{Resposta:S=600m}}$
