Question

The world's highest fountain spews water to a height of 170 m. What is the initial speed of the water? How long does it take for the water to reach the maximum height?

Answer 1

in this problem you know your accelartion, velocity final, and distance..and you are looking velocity intial which formula do you think you should use?

Answer 2

vf^2=vi^2+2ax..i beleive this formula would work out...plug in the values and solve for velocity intial

Answer 3

velocity final:0m/s
velocity intial:?
acceleration: 9.8 m/s^2
distance:170m
