Question paper:

Mark scheme:
https://filestore.aqa.org.uk/resourc...-73572-SMS.PDF

I've got both 15(a) and 15(b) correct,
but I don't understand 15(c) at all
I tried 15(c) again and read the mark scheme
but I don't understand the mark scheme and how to get the anwer for 15(C).
Can anyone please help? Thank you so much!

Gravity (acceleration) is a constant force. So when there are no other forces, the body will accelerate (vertically) with constant acceleration. When the velocity is zero, there is no air resistance as it is a function of velocity. So differentiating the initial velocity gives the acceleration and hence gravity.
