$1\mathrm{.}1\mathrm{.}6$ A vector equation can $be$ reduced $to$ the form $A=B.$ From this show that the one vector

equation $is$ equivalent $to$ three scalar equations. Assuming the validity $of$ Newton's

second law, $F=ma,as$ a vector equation, this means that $a_x$ depends only $on{F}_x$ and

$is$ independent $of{F}_y$ and $F_z.$
