Interesting way of advertising.
I've just had a go at replicating this - took me 10minutes to do (bearing in mind I've 7 years+ of Photoshop Experience)
Citruspers was on the right track, however like the example you posted I suggest that you cut out the main image either by mask or using the eraser to erase the background then duplicate that layer. On the layer at the bottom of the image (so in reality, the layer you did the cut out on) you need to apply a motion blur filter to it. This is done by going to Filter>Blur>Motion blur. I set mine to 0 degrees and about 100 pixels.
When you do that you'll notice that blur occurs on both sides of the image. To sort this simply move the layer with the blur applied as many pixels as needed to one direction in order to have one clean edge and one blurred edge. My attempt is as below:
My blur is quite strong, of course it's down to your taste and what you're after, but if you wanted the blur to be less subtle then all you have to do is reduce the opacity of the blurred layer to say around 50%
Hope that helps.
