## Conservation of Momentum - Module 5 - PHYS 131-OL ### 2. Bouncy Balls Collision **Scenario:** You and your friend are rolling bouncy balls with the same mass toward each other. - **Your ball's initial velocity:** \( 8.15 \, \frac{m}{s} \) - **Friend's ball's initial velocity:** \( 6.38 \, \frac{m}{s} \) (in the opposite direction) **After the collision:** - **Your ball's final velocity:** \( 6.12 \, \frac{m}{s} \) (back toward you) **Questions:** **a. Calculate the final velocity of your friend's ball.** **b. Determine if the collision is elastic or inelastic using mathematical proof.** ### 3. Train Cars Collision **Scenario:** Two train cars are moving in the same direction down a track. - **First Car:** - **Mass:** \( 2400 \, kg \) - **Velocity:** \( 2.85 \, \frac{m}{s} \) - **Second Car:** - **Mass:** \( 3900 \, kg \) - **Velocity:** \( 3.85 \, \frac{m}{s} \) **Post-collision details are missing in the given image.**
