Question 1020997: Hello, I am having trouble with a Word problem/quadratic equation. "A company manufactures high-powered fountains that can be used to create water shows set to light and music. The company makes 3 models, each can launch a vertical stream of water to a different height, as indicated in the table below . Model A Model B Model C
Height(ft)----------- -77---------100---------240
time to fall(s)---- --2.194---- ? ---- ?
Initial velocity (ft/s)----70.2---------?-----------123.9 ** I need to find the 3 missing values (time water would take to fall from each height in the table back to its starting level for models B & C, and the initial upward velocity required for model B to launch the water to its maximum height, and create a function that will give the minimum initial upward velocity (v) required to launch water to any give height (h).
