Any info/resources on calculating the hydrodynamic force on an object when it hits the water surface with constant velocity?

The force on an object being lowered into water can be calculated using the formula F = ρVg, where F is the force, ρ is the density of the water, V is the volume of the object, and g is the acceleration due to gravity.
The force on an object being dropped into water is affected by the density of the water, the volume and shape of the object, and the acceleration due to gravity.
The shape of the object affects the force on an object being lowered into water because it determines the volume of the object. Objects with a larger volume will experience a greater force when submerged in water.
Yes, there is a difference in the force when an object is dropped into still water versus moving water. This is because when an object is dropped into still water, it displaces the water and creates a downward force equal to its weight. However, when an object is dropped into moving water, the force will also be affected by the speed and direction of the water's flow.
The force on an object being dropped into water can be used in practical applications such as designing structures that will be submerged in water, calculating the impact force of objects falling into bodies of water, and understanding the forces involved in diving and swimming activities.
