he means after doubling occurs, so between 83-85/90.

Doubling?

ahhk lol

Thanks so much for the post Mao,

The only answer I'm confused about is question 11 in motion.

I figured the (total) max height of the parabolic path was 135, and to get the height of the cliff you had to subtract 45m from 135 to get 90m.

Can anyone please go through the question for?

Thanks again

its 45 metres to go, and to go down it was 180m iirc, so the final height is like 180-45.

When you sub into the constant acceleration formula, the value of x you get is the displacement, therefore it already gives you the "h" value.

AH! it's so obvious now!

Oh well one wrong!

Thanks Truetears appreciate the quick reply mate
