Maybe you should enable the physics for the water as you did with the floor and the player.

game.physics.enable(floor, Phaser.Physics.ARCADE);

ok but now it is giving me this error: Cannot call method 'getFirstDead' of undefined on line 97 what am I doing wrong there?

Overwriting your group with a sprite is a bad thing.

water = water.getFirstDead();

First: make a firstDeadWater variable outside the update loop and

firstDeadWater = water.getFirstDead()

Use this variable instead of water.

Groups are a collection of objects. They have no physics body of their own, no texture of their own, no input handling.. they're just like bags of objects, so as such you can't apply any velocity to them.

Although this is a good time to point out - do you realise you can add children to a Sprite too? So you could have a parent sprite, that has a physics body, and then just add children to it (Sprite.addChild) that will move quite happily along with their parent. Note that should you collide the parent sprite it's children will be ignored in that check.
