Three events are observed at a baseball game: (A) A baseball is thrown by a pitcher. It starts from rest and is traveling at +38 m/s as it flies toward the catcher. (B) A baseball is traveling at +38 m/s when it enters the catcher's glove and stops. (C) A baseball is traveling at +38 m/s when it hits a wall and bounces away from the wall at -38 m/s. In which case(s) does the change in the momentum of the baseball has the largest magnitude? O Only (C) O Only (B) O Only (A) O Both (A) and (C) O Both (A) and (B)A 9-kg object is at rest. Suddenly, it explodes and breaks into two pieces. The mass of one piece is 6 kg and the other is a 3-kg piece. Which one of the following statements concerning these two pieces is correct? O The speed of the 6-kg piece will be twice that of the 3-kg piece. O The speed of the 6-kg piece will be one eighth that of the 3-kg piece. O The speed of the 3-kg piece will be twice that of the 6-kg piece. O The speed of the 3-kg piece will be one fourth that of the 6-kg piece. O The speed of the 6-kg piece will be one forth that of the 3-kg piece
