## Homework Equations

## The Attempt at a Solution

I don't know how to deal with the q1 part. q2 = u* =u x sqrt(... so that is clear.

Normally I just substitute the expression for u in terms of u* (= f* )and t in terms of t* in [tex] \frac{ du }{dt } [/tex] but how should I deal with the differentiation of the q1 -term?
