Generally, candidates reacted to the given numerical satisfactorily. However, some
candidates failed to go further to determine the height from the ground as demanded by
the question by adding 50m.
The expected answer is:
v2 =u2 - 2gx
At maximum height v = 0
o = 302 - 2 x lOx
o = 900 - 20 x
x = 45m.
Height from ground = 50 + 45
= 95m
