Well they had 1-2 questions that were hard (well not hard but tricky) however i don't think it was harder than the past papers.

the method i use gave me an integer, i think it was 3 can't really remember i used the euation ut+1/2at^2, and both particles will have the same distance but one of them will have the "t" as (t+1) because it was thrown 1 sec after the other which was thrown when t=0.
so it was ut+1/2at^2=u(t+1)+1/2a(t+1)^2 and then solve that. t should be given then.

it wasn't t+1 the time was half a second later i forgot the numbers XD saw the correct number on a copy of the paper online but the idea still remains the same just change the +1 to +0.5
