To remember:

Hyperconjugation is the stabilising interaction that results from the interaction of the electrons in a σ-bond (usually C-H or C-C) with an adjacent empty or partially filled p-orbital or a π-orbital to give an extended molecular orbital that increases the stability of the system. Further information.

The proposed systems to take into account.

Looking at the resonance structures (which is a synonym of mesomeric effect) of the propene

and acetic acid

Therefore, in hyperconjugation analysis you need to look at the position of the electron density. Not the vicinal hydrogen.

Moreover and with the aim to give a complete answer, the hyperconjugation of the acetic acid can be very well understood at here.
