Ball A has a mass of 2 kg, and is traveling at 2 m/s to the right. Ball B has a mass of 3 kg, and is traveling at -4 m/s (to the left). The balls collide, and Ball A moves off to the left at -5 m/s. What is the momentum and velocity of Ball B after the collision? Please show your work!

Which one of the following research methods can show cause and effect

Sodium chloride, nacl, is formed when a sodium atom transfers its electron to a chlorine atom. the difference in charge between the two atoms creates a(n) attraction that bonds them together.

In a system with only a single force acting upon a body, what is the relationship between the change in kinetic energy and the work done by the force? answers: work is equal to the change in kinetic energy.work depends on the square of the change in potential energy.work is equal to the negative of the change in kinetic energy.work is equal to the square of the change in kinetic energy
