the time taken by the particle to reach bottom is given by
\[ s = ut +{1 \over 2}at^2, u=0, \\
s = {1 \over 2}at^2\\
a = g \cos 60 = {g \over 2}\\
2h = {g \over 4}t^2 \\
t = \sqrt{8h \over g}\]

we use this formula
\[ s = ut + {1 \over 2}at^2 = {1 \over 2} {\sqrt 3 \over 4}g {8h \over g} = \sqrt 3h\]
