1. The problem statement, all variables and given/known data
A can has two vertically aligned holes in it. The height of the fluid is h, and the heights of the two holes are h1 and h2.
a) Show that the two streams of water will hit the ground at the same spot when h = h1 +h2.
b) If you had such a can, how would you keep h constant as you verify the above relationship?
2. Relevant equations
Bernoulli's Equation http://en.wikipedia.org/wiki/Bernoulli's_principle
Bernoulli's Principle- Essentially, where velocity is high, pressure is low. Where velocity is low, pressure is high
A1V1 = A2V2 The cross sectional area (A) multiplied by velocity (V)
3. The attempt at a solution
The solution has something to do with projectile motion in the x direction, and in the y direction. To be perfectly honest, I was in regular physics at the time they learned that concept. I was fed up with the slow learning, and decided to enroll in AP physics.
