I am trying to format solutions for an exam paper. 
Is it possible to remove the padding from the top? The environment this is written in is:
\newenvironment{answer}[1]{%
\begin{solutionordottedlines}[#1]
\begin{minipage}[t][#1]{\textwidth}
}{%
\end{minipage}\end{solutionordottedlines}}
And my code is:
\part[1] initial vertical velocity $\vec{u}_{y}$ of the ball
% 1 mark: case one/two calculation and why
% 1 mark: the implication of them being equal
\begin{answer}{2cm}%
\begin{align}
\vec{v}{y}&=\vec{u}{y}+\vec{a}{y}t\
0&=\vec{u}{y}-9.8\times2.5\
\therefore \vec{u}_{y} &= 9.8\times2.5 = \SI{25.5}{\metre\per\second};\text{up}
\end{align}
\end{answer}
