Answer to Question #269521 in Physics for Kev

Question

When two cars collide, the forces they received are equal but opposite. What about their acceleration?

Answer 1

$\vec F_1=-\vec F_2$

$\vec a_1=\vec F_1/m_1$

$\vec a_2=\vec F_2/m_2$

$|\vec F_1|=|\vec F_2|=F$

$a_1=F/m_1$

$a_2=F/m_2$

If $m_1>m_2$ then $a_2>a_1$
