1 Find the velocity of the CoM of the System A 3kg ball moves at 3 m/s towards a 1 kg ball at rest that is 100 meters away 3 kg 1 V= 3 m/s V= 0 Vcm = Σmv/Σm = {3kg x 3 /s + 0} / 4 kg = 2.25 m/s Xcm

2 Find the velocity of the CoM of the System A 3kg ball moves at 3 m/s towards a 3 kg ball at rest 3 kg V= 3 m/s V= 0 Vcm = Σmv/Σm = {3kg x 3 /s + 0} / 6 kg = 1.5 m/s Xcm

3 Find the velocity of the CoM of the System Two 3kg ball move toward each other at 3 m/s 3 kg V= 3 m/s Vcm = Σmv/Σm = {3kg x 3 m/s - 3kg x 3m/s } / 6 kg = 0 m/s Xcm

4 Find the velocity of the CoM of the System Two 3kg ball move in the same direction at 3 m/s 3 kg V= 3 m/s Vcm = Σmv/Σm = {3kg x 3 m/s + 3kg x 3m/s } / 6 kg = 3 m/s Xcm

5 Find the momentum of the CoM of the System A 3kg ball moves at 3 m/s towards a 1 kg ball at rest that is 10 meters away 3 kg 1 V= 3 m/s V= 0 Pcm = MVcm Vcm = Σmv/Σm = {3kg x 3 /s + 0} / 4 kg = 2.25 m/s Pcm = 4 kg x 2.25 m/s = 9 kg m/s Xcm

6 Find the momentum of the CoM of the System A 3kg ball moves at 3 m/s towards a 3 kg ball at rest 3 kg V= 3 m/s V= 0 Vcm = Σmv/Σm = {3kg x 3 /s + 0} / 6 kg = 1.5 m/s Pcm = MVcm Pcm = 6kg x 1.5 m/s = 9 kg m/s Xcm

7 Find the momentum of the CoM of the System Two 3kg ball move toward each other at 3 m/s 3 kg V= 3 m/s Vcm = Σmv/Σm = {3kg x 3 m/s - 3kg x 3m/s } / 6 kg = 0 m/s Pcm = MVcm Pcm = 6kg Vcm = 0 Xcm

8 Find the momentum of the CoM of the System Two 3kg ball move in the same direction at 3 m/s 3 kg V= 3 m/s Vcm = Σmv/Σm = {3kg x 3 m/s + 3kg x 3m/s } / 6 kg = 3 m/s Pcm = MVcm Pcm = 6kg x 3 m/s = 18 kg m/s Xcm
