Answer 1

To determine the kinetic energy of the baseball when it hits the window, you would need to collect the following two pieces of information:

1. **Velocity of the baseball right before it hits the window**: This is necessary to calculate the kinetic energy, as kinetic energy is dependent on the square of the velocity.

2. **Mass of the baseball**: The mass is needed in the kinetic energy formula, which is given by KE = 0.5 * mass * velocity^2.

The mass of the window and the velocity after hitting the window are not necessary for calculating the kinetic energy of the baseball at the moment of impact.
