A fire hose is shooting water at a refrigerator at 10 kg/s with a velocity of 10 m/s. This flow is perpendicular to the surface and all water flows off parallel to the surface (ie no "x" direction in outflow). The friction on the ground which must be overcome to cause the refrigerator to move is 50 N. The refrigerator is 2 m tall and 0.8m wide and 1 m deep. It weights 200 kg (which you may assume to be evenly distributed). Will it move? If no what is the initial acceleration?

Fluid Dynamics

The study of the flow of gases and liquids, usually in and around solid surfaces, is known as fluid dynamics in physics and engineering. Fluid dynamics, for example, can be used to evaluate the movement of air through an airplane wing or the surface of a vehicle. It can also be used in ship design to increase the speed at which ships pass through water.
