The first step I would take with this problem is solving for all unknowns. Thankfully there is just one, A. You are given the equation along with two known points(t=0 and 2.6). After that, you should recall that acceleration is the change in velocity over time so a = dv(t)/dt. Finally, for any exponential function that takes the form f(x)=aebx+c the asymptote of that function has the value c.
