About once every 30 minutes, a geyser known as old faceful projects water 11.0 m straight up into the air.
use g = 9.80 m/s2, and take atmospheric pressure to be 101.3 kpa. the density of water is 1000 kg/m3.
(a) what is the speed of the water when it emerges from the ground? m/s
(b) assuming the water travels to the surface through a narrow crack that extends 9.00 m below the surface, and that the water comes from a chamber with a large cross-sectional area, what is the pressure in the chamber?
