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