About once every 30 minutes, a geyser known as old faceful projects water 18.0 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. what is the speed of the water when it emerges from the ground?

Speed of the water that emerge out of the pipe is 18.8 m/s

Explanation:

Since we know that water drops projected upwards to maximum height of 18 m

So here we can use kinematics equations here

here we have

so we will have

answer; /// i believe that the correct answer is (c)

i would say the answer is food.

hope this !
