Question 1182163
.


Linear momentum is the product of the mass of the body (of the air in the given volume) by its velocity.



Using the coherent units is of crucial importance.



If you use kg/m^3 for the air density, the consistent unit for the speed (velocity) is m/s,

so all other velocity units must be converted to m/s.
