I was wondering how this involves using implicit differentiation?

v = v(t)

a= a(t)

v=sqrt(8s+16)

since v(t) = sqrt(8s+16) do i have to use implicit differentiation? How would finding it help me show that acceleration is constant?

Also, for Part C, do i just graph v(t) = sqrt(8s+16)

I'm lost in how i can use implicit differentiation to solve this.
