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

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer

total distance/total time

(85 + 82)/(5+3)

167/8
