I am horrible at physics and am struggling to pass, so you may see these often. I have no clue how to approach this problem. Rather I know that the pressure difference between the outside and inside will result in a net force out which will cause the water to exit as speed v. However, I cannot figure out how to work out the math.
A rectangular trough, 1.9 {\rm m} long, 0.80 {\rm m} wide, and 0.40 {\rm m} deep, is completely full of water. One end of the trough has a small drain plug right at the bottom edge. When you pull the plug, at what speed does water emerge from the hole?
any help will be appreciated, a walk through of the equations is even more important for me to reach an answer. I am the kind of person that needs equations explained through before i begin to understand them. The prof failed that point, though through no fault of his own.
***note I tried to use Bernoulli's Equation, but can not figure out what I am doing wrong as i cannot isolate a term***
