Homework Statement
Suppose the water fountain in fountain hills, Arizona, rises 150ft above the lake. Neglecting wind effects and minor losses, determine the velocity at which the water is ejected
did you make an attempt at this problem?
I assume what you mean is that water is squirted directly upward so it reaches a peak 150 ft above the jet where it exited. If that is the situation, it is the same as shooting a projectile straight up.
yes, i tried using this formula, but i don't know if its right
V^2 = Vo^2 + 2AD
A = 9.8m/s^2
V^2 = 0^2 + 2(9.8)D
V^2 = 19.6D

Nope, the initial velocity is not right. The water rises up to 150 ft. What does this tell you?
..and also, the given unit is ft. Then, g = 32 ft/s/s
So it should be like this
V^2 = Vo^2 + 2AD
A = 32 ft/s
V^2 = Vo^2 + 2(32)150
then what is the value fo V^2
