questão de física para treiarem

Answer 1

$\underline{\text{For{\c c}a resultante}} \ (\text F_\text r) : \\\\\text F_\text r = \text {m.a}$

$\underline{\text{carrinho de 100 kg}}: \\\\ \text{F}_\text r = \text T \\\\\ 100.\text 2=\text T \\\\ \huge\boxed{\ \text T = 200 \ \text N \ } \checkmark$

$\underline{\text{carrinho de 40 kg}}: \\\\\ \text F_\text r = \text F - \text T \\\\ 40.2 = \text F -200 \\\\ \text F = 80+200 \\\\ \huge\boxed{\ \text F = 280 \ \text N\ }\checkmark$
