A golfer faces an approach shot from the fairway to an elevated green 6 metres above where she stands. She uses a pitching wedge with a loft of 70 degress and the ball leaves her club traveling at 35 m/s.
What is the maximum height the ball reaches above the level from which it was hit?


What I did:
vf^2=vi^2+2ad
0=(35sin70)^2+(2*-9.8)d
d=55 m

i was just wondering if i have to take the 6 metres into account?

No, since the question asked:

There is no need to take into account the initial height. However, if the question were to inquire about the ball landing then you would need to taking into account the additional 6m.
