momentum is measured by the product of mass and velocity of the object. As You have mentioned that the body is stationary then the velocity is zero. So the momentum of the body is 0.
hope this helps
infiltration and evaporation
Their momentum is the same.
momentum of dolphin=50kg*16.4m/s=820kg*m/s
momentum of elephant=4100kg*0.20m/s=820kg*m/s
