The problem reads: A particle moves along the curve given by y=sqrt(t^3+1). Find the acceleration when t=2.
Kevin wrote:second derivative again. first derivate would be 1/2(t^3+1)^(-1/2)(3t^2).
Would this workout to be 1/(3t)^(-1/2)(6t)?
I have tried this a few different ways but have not gotten the correct answer yet (multi choice)
Thank you very much, I have been working on this all day
