basically you find the individual force on each part and then add them to find the net force, but then that force is shared between the two masses so you have to divide the force by their total mass to find the acceleration

Generally, 2023 trial papers>2022 trial papers>2020 trial papers>2021 trial papers in terms of difficulty.

The reason for this I believe is that trial papers tend to be written based on the precedent set by the previous years’ HSC

i think 2021 was easiest cause it was done during lockdown online, so it wasn't a proper trial
