## Homework Statement

Tank (mass M) contains water

(mass m). L is distance from

centre of mass of container to

pipe.(x) is noted as the direction to the right. Pipe is small compared to

tank. Tank is sitting on a frictionless surface

Open the tap, water flows out.

After, where is the tank and

which way is it moving?

Explain your answer in terms of

forces on the tank.

see link two posts down for picture...

I need to find

expression for the distance travelled

- expression for the final velocity

## Homework Equations

## The Attempt at a Solution

I assume as the water flows out, the tank would move to the left as the water is flowing out of the tank to the right so there would be an equal but opposite in direction force acting on the tank. Hence the tank moves to the left.

But I don't know how to work out where the tank is, given There is no variables to work with.

Please correct anything that is wrong with my logic above?
