Question
1. Tom and Jane are sitting at opposite ends of a boat. Tom is on the left and Jane is on the right. Tom tosses a heavy ball right-ward to Jane with a velocity of 3m/s and Jane catches it. Then Jane throws the ball back left-ward to Tom with a velocity of 6m/s and Tom catches it. Which statement below best describes the motion of the boat itself during this process? (neglect any friction of the boat with the water) Hint: consider what must happen to the center of mass of the entire system of boat + ball + people. A. The boat does not move during this process. he boat drifts first to the left and then to the right, returning exactly to its C. The boat drifts first to the left, then to the right. It ends up to the right of where D. The boat drifts first to the left, then to the right. It ends up to the left of where E. The boat drifts first to the right, then to the left. It ends up to the left of where riginal location after Tom catches the ball. it started it started it started. Page 2 of 7Explanation / Answer
Since initially the center of mass was at rest and there is no external force acting in the system.
When Tom throws the ball towards Jane boat will move in opposite direction and when it will be caught by Jane it will stop in such a way that center of mass will not shift.
Similarly when Jane throws the ball towards Tom same thing will happen and finally boat will come to the initial position.
So option B is correct.
