The numbers: 5 oz baseball vs 6.75 oz softball. This is the energy (joules) that must be dissipated when bringing the ball to a complete stop. Some will be dissipated in the ball, the rest in whatever is struck. How much energy is expended in the ball depends on its constuction. I've highlighted roughly equal energies for the baseball and softball.
