Essa é a última, alguém ajuda pfvvv

Answer 1

Formula da distancia final $S=8,5+2T$

Basta substituirmos os valores para completar a tabela

T(s)=0

$S=8,5+2T\\\\S=8,5+2\cdot 0\\\\S=8{,}5M$

T(s)=4

$S=8,5+2T\\\\S=8,5+2\cdot 4\\\\S=8{,}5+8\\\\\boxed{S=16{,}5M}$

S(m)=21,5

$S=8,5+2T\\\\21{,}5=8,5+2\cdot T\\\\21{,}5-8{,}5=2T\\\\\\13=2T\\\\T=13\div 2\\\\\boxed{T=6{,}5s}$
