Question

these are also called u-shaped, blowout, or hairpin dunes, and tend to form where vegetation covers the sand.

Step-by-step explanation:

Winds may erode a section of the dune, pushing the sediment leeward or downwind. The vegetation will hold back the arms of the dune, so that the dune points in the leeward direction, or downwind.
