Why do scientists track virus mutations and how might tracking these variants be helpful in preventing and treating the virus?(coronavirus)

Different variants = certain symptoms and effects of the virus that cannot be prevented by the "basic" or "original" vaccine. So tracking the different variants would allow scientists to also account for those effects when creating a 2.0 vaccine or treatment.

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
