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
