I checked paper 21, no momentum question, however paper 23 q.8 has something about a gas molecule (not a ball, read the questions carefully please
) that hits a wall, and there is a reason why momentum actually change, recall that momentum is actually a vector quantity so change in direction will change velocity, thus changing momentum however, K.e is scalar and is not affected by directional change- Messages

A 0.216g sample of an aluminium compound X reacts with an excess of water to produce a single hydrocarbon gas. This gas burns completely in O2 to form H2O and CO2 only. The volume of CO2 at room temperature and pressure is 108 cm3.
What is the formula of X?
A Al2C3 B Al3C2 C Al3C4 D Al4C3
Someone explain this please, the ans is D tho

I found this from the marking scheme
The idea of headwind on outward journey
OR tail wind on return journey
OR shorter route on return journey
OR air friction is less
OR idea of less weight
NOT flies slower.

If this book comes with a CD then u need to check it, the answers to the end of chapter questions are usually there. Otherwise, if the question reference is given the then you can always open up the marking scheme for it
Thanks to hamnah, for finding it out ^
