WD was 8/5mg and GPE was 24/5mg therefore change in KE was 16/5mg
1/2v² was equal to 16/5g + 1/2(5)²
therefore v was 9.4 2sf or 9.37 3sf
I think you forgot to multiply by a 1/2 before you square rooted to find v as that gives you 6.63 ...

I’d say you’d lose two max cause you had an equation all in v you just forgot to multiple by 2 as it was 1/2 v² = .... not v² so definitely lose A1 mark but might have got the method mark for the right equation
