A falling body dropped at a velocity

60 m s^{- 1}

. Find the initial height

h

, if the relation between the velocity and the initial height

h

v = \sqrt{2 h g}

. Use

g = 10 m s^{- 2}

for acceleration of gravity.

The initial height is between

150 m

and

200 m

The initial height is smaller than

100 m

The initial height is between

100 m

and

150 m

The initial height is bigger than

200 m
