Parallel circuits are mostly used in houses because if you turn one light off the rest stay on. While with a series circuit, if you turn one light off, all the lights turn off as well because they are all connected to one circuit (series). Parallel is usually 2 or more circuits which is why it lets you turn one thing off and everything stays on.
The only thing acting as the roller coaster gets to the bottom is gravity thus
acceleration is 9.81
so u use the formula
vf^2 = vi^2 + 2abetaD
thus
distance = vf^2 - vi^2 divided by 2a
so 26^2 - 0^2 divided by 2(9.81m/s)
equals 676 divided by 2(9.81m/s)
= 34.45463812m
then use the appropriate 3 sig digs
so 34.5m
hopes this helps
