when you combine two 1d analysis (x and y separately), you get 2d

velocity of light has nothing to do with the mass m thrown from the origin at t=0 with initial three momentum p0 in the y direction, with additional constant force in x direction. as usual, the hardest part of the question is to understand what they are talking about. the question is actually...

potato-potato the pressure before the plug is released is the one to create the force of the flow as the plug is released; split seconds; after the plug is released everything starts moving because of this force we can agree to disagree btw, the question is will the system trip over, or will it...

You are making it too complicated for no reason; what is speed of light doing in your attempt? Observe vertical and horizontal motion separately and u will see what needs to be done. #OnlyPerfectPracticeMakesItPerfect #MathAndPhysicsHelpOnline

which is the force when the plug is released; which will be the product of the cross sectional area of the pipe multiplied with the pressure at the pipe level

the flow is not constant; it will decrease as the fluid drains

I am not sure about the accuracy of the EQ haruspex is pointing to. But for sure you need to start with the pressure when the plug is ON. After unplugging, everything will decrease with the time ( the pressure and both velocities ) , until there is no liquid going through pipe. For the...

Read about Doppler's effect; the shock wave is there because the source is always ahead of the sound wave it creates; behind the source, there will be a region where waves superimpose; sketch the moving plane, sketch few wave fronts and you will see how they combine. Look up Sonic Bum.

u mean before the rain starts? :-)
