The units for pressure ( p ) in terms of SI base units are known to be
. For a physics class assignment, a student derives an expression for the pressure exerted by the wind on a wall in terms of the air density ( ) and wind speed ( v ) and her result is p = v 2. Use SI unit analysis to show that her result is dimensionally consistent. Does this prove that this relationship is physically correct
