A fountain at a city park shoots a stream of water vertically from the ground. The function y=-8x^2+16x models the height of the stream of water in feet after x seconds. A. What is the maximum height of the stream of water?

B. At what time does the stream of water reach its maximum height?

C. For how many seconds does the stream of water appear above ground?

1.5%

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
