A water balloon is observed to emerge from an open window of a
gymnasium. The window is 9.5 m above the ground. Through miracles
of technology (involving doppler radar and automated video
analysis), it is determined that the balloon leaves the window with
a speed of 12.5 m/s at an angle of 45∘45∘ relative to
horizontal.
(A) How much time elapses from when the balloon is passing through
the window to when it hits the ground? s
(B) How far from the wall does the balloon hit the
ground? m
It is determined that someone within the gymnasium threw the
balloon from the floor level of the gymnasium,which is level with
the ground outside.
(C) Assuming the launch point is from the floor level, how far from
the wall was the balloon launched? m
