Make a prediction about what will happen in the following scenario:
Two bowling balls collide (elastic collision) both have the same mass. If Ball A is moving to the right a 3 m/s and Ball B is moving to the left at 2 m/s. What can be said about the velocity of ball A after the collision?
In an elastic collision, the total momentum and total kinetic energy of the system are conserved. Since Ball A is moving to the right and Ball B is moving to the left, it is expected that they will collide and change direction.
Since both balls have the same mass and are moving towards each other with different velocities, they are likely to bounce off each other after the collision. Ball A, which is moving faster, will likely slow down, while Ball B, which is moving slower, will likely speed up.
To determine the exact velocities after the collision, we need to know more about the relative masses and the coefficient of restitution of the balls. However, based on the given information, we can predict that after the collision, Ball A will have a velocity to the left, though it will be slower than its initial velocity, likely between 2 m/s and 3 m/s.
