Is r defined anywhere?
@viennamotley, the question means that })
is the position vector from the origin of the projectile at any time 
.
You start from} = -g\overrightarrow{j})
and integrate to get })
where, at time 
, } = \left|\overrightarrow{v(0)}\right|\left(\cos{\alpha}\overrightarrow{i} + \sin{\alpha}\overrightarrow{j}\right))
. Then integrate a second time to get subject to the constraint that } = 0\overrightarrow{i} + 0\overrightarrow{j})
.
You start from
