would you need to collect? Select two KE = ‡
-mu?
(4 points)
• velocity of the baseball after it hits the window
mass of the window
velocity of the baseball right before it hits the window
mass of the baseball

Answer 1

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

1. Velocity of the baseball right before it hits the window: This is necessary because the kinetic energy depends on the velocity of the baseball. The formula for kinetic energy is KE = (1/2)mv^2, where m is the mass of the baseball and v is its velocity.

2. Mass of the baseball: This is also necessary because the kinetic energy depends on the mass of the baseball. As mentioned above, the formula for kinetic energy is KE = (1/2)mv^2, where m is the mass.

Therefore, by knowing the velocity of the baseball right before it hits the window and the mass of the baseball, you can calculate the kinetic energy of the baseball when it hits the window.
