you should tell what thing you would like to find at which point of roller coaster.
Suppose you have the lowest point of track on the ground and you would like to find the speed at the lowest point of track.
Applying conservation of energy

$\displaystyle mv^2/2=mgh$
$\displaystyle v=\sqrt{(2)(10)(171)}$
