It is given that the 
co-ordinate of 
increases at one unit per second. That is,
}{dt} = 1)
We want to use part iii) to answer the question. That means we need to find
.
}{dt} \cdot \frac{dp}{d(ap^2)})
And,
} = \frac{1}{\frac{d}{dp} ap^2} = \frac{1}{2ap})
So,
Then substitute back into iii) and a similar process for
will give
}{dt} = -\frac{q^2}{p^2})
