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?

The astronauts on the space shuttle flights experienced an acceleration of 29 m/s2 (about 3 "g's") during lift-off. what upward force must the astronaut's seat apply to the astronaut in order to cause this acceleration? assume the astronaut's mass is 70 kg, and compute this force when the acceleration is near the earth's surface so their weight equals latex: mg m g .
