The four-step solution procedure:<\/p>\n

    \n
  1. Step 1 – FBDs<\/strong><\/em>: Draw individual free body diagrams (FBDs) for A and B, along with an FBD of A+B. Since you have two impacts occurring at the same time, identify the “n” direction for each impact (they are different for each impact).<\/li>\n
  2. Step 2 – LIM and COR<\/strong><\/em>\n
      \n
    • For the impact of A with the bumper, use the coefficient of restitution (COR) equation.<\/li>\n
    • For the impact of A with B, use conservation of linear momentum in the n-direction and the COR equation in the n-direction.<\/li>\n<\/ul>\n<\/li>\n
    • Step 3 – Kinematics<\/strong><\/em>: None needed.<\/li>\n
    • Step 4 – Solve<\/strong><\/em><\/li>\n<\/ol>\n
