Odesolve "too few initial conditions"

[Laurengineer]

I've been trying to get to grips with odesolve, but I keep getting the error "too few initial conditions"

As far as I can see I have two equations to solve and two initial conditions - could someone help me work out what I'm missing please?

Hi,

Odesolve knows nothing about units
