  2. How to find final velocities of bodies after elastic 8 inelastic collision 2


  3. Example - Completely inelastic collision; balls moving on a frictionless surface initial P final Before the collision, the particles move separately 22i vii mo For m1=0.3kg,m2=0.5kg After the collision, the particles move together. (0.3 X2)i + (0.5X-1 (0.3)+ (0.5 m S mi m2 0.125 m/si


  4. Energy loss in this example: Before the collision, the particles move separately For m0.3kg, m 0.5kg m1 2 = 0.125 m/s ! AE -((0.3)+ (0.5))0.125 0.3 2(0.51 After the collision, the particles move together. =-084 J m1 m2

Example- completely elastic collision, balls moving on a frictionless surface i initial i final Before the collision, the particles move separately m,v i initial ii final 2 2i 2 2 For 1- d motion, after some algebra: After the collision, the particles continue to move separately with new velocities. im 2 m 2 1 m1 t m 2 V2f 1m 1m m1tn
