It will mount and work, but it will not autofocus.
You need this one. It's awesome, I have it.

Or this one, which is made for DX sensors but is a little slower reacting and more cheaply made.
Yes and No.
It will work, but it will not autofocus as the D5100 does not have an in-camera focus motor.
Besides, that lens is rumored to actually be made by Tamron for Nikon. So perhaps look at a Nikon AF-S 55-200mm or AF-S 55-300mm, which will autofocus on your D5100.
So keep this in mind:
AF lenses will not autofocus on your D5100.
AF-S lenses will autofocus on your D5100.
Will it fit - Yes
Will it give you automatic exposure - Yes
Will it give you autofocus - No
Will it give you focus confirm - Yes
