Question 1 2 pts Ball A and Ball B both have masses of 0.5 kg . Ball
A
has an initial speed of
4.0(m)/(s)
to the right and Ball
B
has an initial speed of
2.0(m)/(s)
to the left. If the two have an elastic collision, which statements below are true? (Check all that apply.) Both balls move to the left after the collision Mechanical Energy is conserved in the two ball system Ball A has zero velocity after the collision Ball A's final speed is
2.0(m)/(s)
to the left Both balls move to the right after the collision
