Find the particles position s at time t.

1.) $\displaystyle v=9.8t+5, s=10$ when $\displaystyle t=0$

2.) $\displaystyle a=32, v=20$ and $\displaystyle s=5$ when $\displaystyle t=0$

I think I got the first question, I ended up with $\displaystyle s(t)=4.9t^2+5t+10$, but I don't know what to do with the second problem. Any help is appreciated, thanks.
