Steph is pouring milk onto the ground at a constant rate of five kilograms per second. The milk exits at a distance of 80 centimeters above the floor and has an initial velocity of three meters per second directed horizontally. Expressed in Newtons and rounded to the nearest integer, find the magnitude of the force that the milk stream exerts on the ground, neglecting air resistance and assuming that its collision with the ground only cancels out the vertical component of the milk's velocity.
