2. A person diving into a swimming pool.
= Agent exerting force is water.
A diving person falls into the water by the gravitational pull.
Once inside the water the gravitational pull is overcame by the buoyancy of the water.
= This results into an unbalanced force which prevents one from reaching the floor of the swimming pool.
The buoyancy of water equals the upthrust. Upthrust is the force exerted by a fluid on a body once the body displaces some fluid.
