we know the ball has an initial velocity, u = 29ms^-1
and that there is a constant decelleration of 9.8ms^-2
at the maximum height, velocity, v = 0
so we can use the equation V^2 = u^2 + 2as
which implies (29)^2 + 2x(-9.8)s = 0
so 29^2 = 2x9.8xs
so s = 29^2 / (2x9.8)
so s = approx 42.9 m
hope this helps
If this isn't clear enough tell me and I'll try to make it a bit neater and easier to understand

NithishReddy6332: 1) 2.3m 2) 6m 3) 9.8m and 4) 4.9m
YASHOFFICIAL24082004: it is 4.9 answer
NithishReddy6332: how
NithishReddy6332: could you plz explain me the answer
YASHOFFICIAL24082004: it was the approx value see in answer
NithishReddy6332: u kept 42.9 and it is too far from 4.9
NithishReddy6332: can i ask you some more questions related to physics
YASHOFFICIAL24082004: u can
YASHOFFICIAL24082004: sure
NithishReddy6332: i kept questions with a photo
