Calculate the final speeds.
: Since both pucks have identical velocity vectors, the entire system is moving "together" toward the top of the screen. 3. Run the Collision and observe the white trail left by the center of mass.
❌ Forgetting that inelastic collisions still conserve momentum. ✅ Fix: Even if pucks stick together, ( \vecp initial = \vecp final ) holds true.
v sub c m end-sub equals the fraction with numerator sum of m sub i v sub i and denominator sum of m sub i end-fraction equals the fraction with numerator p sub t o t a l end-sub and denominator cap M end-fraction Because momentum ( ) is conserved in both the
