To determine the kinetic energy (KE) 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 using the formula KE = 1/2 mv^2, where v is the velocity.
2. **Mass of the baseball** - This is also needed for the kinetic energy formula, as it represents the mass (m) in that equation.
The other options, such as the mass of the window and the velocity of the baseball after it hits the window, are not required for calculating the kinetic energy at the moment of impact.
