Answer: Less than 45 centimeters, as the ball transforms some of its potential energy into thermal energy and sound energy. Explanation: Although the initial energy (potential energy is preserved), the energy of deformation as the ball strikes a surface creates energy dissipation in the form of frictional heat and audible sound energy. Every time the ball bounces, its height will be less than its previous height.
