@RichInPitt The idea is to see how you think about a novel question you haven’t encountered before. You’ll be helped with any background information needed if you haven’t covered it before.
But many candidates for a Psychology degree will have A level psychology which includes this general material (https://www.cambridgeinternational.org/images/254186-2018-2020-syllabus.pdf).
Similarly the football question is basically about ballistic trajectories and recognizing and characterizing the impact of the forces of gravity, air resistance, etc. on velocity such as whether air resistance is proportional to the speed (https://en.m.wikipedia.org/wiki/Projectile_motion) so you can write down the differential equation you’d need to solve.
It’s somewhat similar to my interview question that I still remember 30+ years later, which was “if you fire a ball under gravity just fast enough so that it orbits the earth and drop another one through the center of the earth, then (ignoring air resistance) which gets to the other side first?”. The trick was to recognize that as an example of Simple Harmonic Motion.
