Question: Answer the following question. LO 15c: What must be true about the coefficient of restitution for momentum and energy to be conserved during an impact? Explain your reasoning.

Problem: Use the figure below to answer the following question.  Assume Ball A has a mass of 0.2 kg while Ball B has a mass of 0.5 kg.  Ball A is initially moving with a velocity of 5 m/s to the right while Ball B is initially moving to the right at 2 m/s.  The coefficient of restitution is . LO 15c: What are the velocities of Ball A and Ball B just after the impact?  Show your work.  Describe the direction beyond a simple +/-. Value Solution Units Direction [sol] [units] [dir] [sol2] [units2] [dir2]
