Using Regula$-$Falsi method determine the xr value of drag coefficient $($c$)$ needed after $3$rd iterations for a parachutist of mass

$m=67kg$ to have a velocity of $45\frac{m}{s}$ after free$-$falling for time $t=12s?$ Consider the root between $12$ and $16.$ You can use this

equation for parachchutistfree$-$fall: $f(c)=\frac{gm}{c}(1-e^{-(\frac{c}{m})t})-v$
