Q$1$ In experiment of Uniform Acceleration Motion you get data from experiment as

Y $($m$)|$Time $($s$)|$T$^2($s$)$

$0\mathrm{.}1|0\mathrm{.}2|0\mathrm{.}04$

$0\mathrm{.}25|0\mathrm{.}23|0\mathrm{.}0529$

$0\mathrm{.}4|0\mathrm{.}3|0\mathrm{.}09$

$0\mathrm{.}55|0\mathrm{.}31|0\mathrm{.}0961$

$0\mathrm{.}7|0\mathrm{.}4|0\mathrm{.}16$

$0\mathrm{.}85|0\mathrm{.}43|0\mathrm{.}1849$

$1|0\mathrm{.}45|0\mathrm{.}2025$

following :

$1-$Plot y versus t$^(2),$ draw smooth curve through the points.

$2-$ Find g from the graph and calculate the error. $($note:

use graph papers $)$
