common guys...you are always bragging bout your Ph.D.'s in Physics ...so common-

I have no clue what you are even asking. If there is no friction then any force applied (water pressure) is going to make acceleration increase indefinitely.

NEI, it depends on the momentum of the water after impact.

it's a transfer of momentum problem

>>2614758
why is the cock cumming blue shit?

>>2614838
I dont know if I'm thinking right...but I think the Mass that is accelerated cannot exceed the speed of the water Ray

>How is the formula to describe the acceleration of this mass is the water Ray shoots against it?

>>2614758
Are you serious?
How old are you?

Restate the problem in a fuckin coherent and quantitative manner, and I may help.

True because the impulse from the water would never reach the object.

He did. I don't see why some people are not capable of understanding this problem.

>>2614882
I'm sorry that you are to ignorant to understand what I mean

>>2614894
thank you...

>>2614898
Maybe it helps you that the water's velocity is 12 m/s

>>2614894

You wrong

hmm... well it's interesing to know that there isn't a formula for this problem...

the reason why I want to have it, is that I want to calculate the how light can accelerate objects

I have some ideas, I want to experiment wih planks constant "h"..

<div class="math"> F = \int \int \rho v (v \cdot n) dA </div>
this can be simpt to
<div class="math"> F = v^2 \rho A = vm </div>
v is the speed of the water relative to the cube
m is the mass fro rate of the water
F is the force on the cube

so <span class="math"> F=m_{cube}a [/spoiler]
<div class="math"> m_{cube}a = v^2 \rho A </div>
<div class="math"> a = \frac{V}{A}m </div>
<div class="math"> a = (\frac{0.03-v_{cube}}{0.05^2 \pi})^2(1000)(0.05^2 \pi) </div>

a = dv/dt so
<div class="math"> \frac{dv}{dt} = (\frac{0.03-v}{0.05^2 \pi})^2(1000)(0.05^2 \pi) </div>

sove this and you have v as a function of t, diferensiate it to get a as a function of t.

wow...thank you..I'll try it out

Question: What can one learn from OP's picture, what is the practical use of being able to understand the answer to the problem?

>>2614970
just use that shit for light

a negro is entering your shop, you wish for the fire brigade to remove him from the premises, will the g-forse inflicted on his body teach him not to enter your shop again?

Apparently I'm a huge newfag here, but what can cause this:

this is basic fluid mechanics

you should read "Basic Fluid Mechanics" by David Wilcox

it will answer all of your questions
