Hi guys help!!!
Two skaters A and B of equal masses are standing on ice, facing each other. Skater A is holding a ball. Then A throws the ball to B and B catches it. Which of the following statements provides the most accurate description of the subsequent motion of the skaters? Assume that the ice surface is frictionless. (a) both A and B will start moving away from each other (b) Both A and B will not move in either direction (c) Both A and B will start moving towards each other (d) Only A will start moving away from B while B stays stationary
Explanation / Answer
First applying conservation of momentum at A, A will move opposite to A then applying conservation of momentum at B , B will start moving in direction of ball so both will move in opposite direction
So a
