(adsbygoogle = window.adsbygoogle || []).push({}); hey, i am a year 11 student trying to complete an assignmnt based on the physics in the amusment park 'dreamworld'

i have been ask to change something about a ride and write about safety and thrill factor this would affect, a chose the giant drop ( a free fall ride )

i am planning to change the height of the ride from 120m to 200m , and now trying to calculate g force

so far:

s = -200m

u = 0

v = ?

t = ?

a = -9.8 m/s

on the internet i found an equation for g force:

a / g = g force

a = change in velocity / change in time

g = -9.8

i calculated velocity first

v^{2}= u^{2}+ 2as

v^{2}= (0)^{2}+ (2 x -9.8 x - 200)

v^{2}= 3920

v = 62.1

now i have velocity i tried to work out time

v = u +at

62.61 = o + (-9.8 x t)

62.61 = -9.8 x t

62.61 / -9.8 = t

- 6.39 = t

and thats it i cannot find a way and i am very confused please help i am still learning :(

thank you
