TLDR: The kinetic energy is determined to be zero.
Kinetic energy is energy of motion; when an object is moving (i.e. it has speed or velocity), it has some amount of kinetic energy. The equation itself looks like so:
KE=1/2(m)(v)^2,
where "m" represents the mass of the object and "v" represents the objects speed or velocity. In this example, the ball has stopped, meaning it has no speed/velocity. This means that the final kinetic energy is determined to be zero or none, due to the lack of motion. Mathematically, you can see this by substituting "0" in for "v" (the ball is stopped):
KE=1/2(m)(v)^2
KE=1/2(m)(0)^2
KE=1/2(m)*0
KE=1/2*0
KE=0 J,
or zero kinetic energy.
Hope this helps! :)

Not sure how to show crisscross method
Make sure adding the charges together=0 and multiply the elements when necessary to balance charge
Solution: Change in state of matter is a physical change because of the physical condition and appearance changes but not the chemical composition.
Answer:
b Van der Waals - Hydrogen Bond - Covalent Bond - Ionic Bond
Explanation:
Generally interatomic bonds are stronger compared to intermolecular forces.
Van der waals and hydrogen bonds are intermolecular bonds that forms between molecules or even compound.
Covalent and Ionic bonds are interatomic forces.
Van der waals forces are the weakest forces of attraction and hydrogen bonds are very strong forces.
Ionic forces are the strongest interatomic forces.
