Answer: Kinetic energy is the energy of an object due to its motion. To calculate the kinetic energy of a baseball when it hits a window, you need to know the mass and velocity of the baseball, as well as the distance it traveled. You can then use Newton's Second Law of Motion (F = m x a) to calculate the acceleration, and then use the equation KE = 0.5 x m x v^2 to find its kinetic energy.
