(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Given, y^{2}= 9x^{3}+ 6x, where x and y are in metres and y is positive.

What is the normal component of the acceleration when x= 3m, [tex]\dot{x}[/tex] = 7ms^{-1}and [tex]\ddot{x}[/tex] = 8 ms^{-2}?

2. Relevant equations

V= V_{x}i+ V_{y}j

V_{x}= [tex]\dot{x}[/tex]

V_{y}= [tex]\dot{y}[/tex]

a= a_{x}i+ a_{y}j

a_{x}= [tex]\ddot{x}[/tex]

a_{y}= [tex]\ddot{y}[/tex]

3. The attempt at a solution

I was fairly confident that my following attempt would yield the correct solution, however it did not. I still fail to see any problems with my attempt, so I thought I'd post it. Any feedback on my work would be greatly appreciated.
