The tennis ball will have more kinetic energy than a Wiffle ball because it has more mass.

Kinetic energy is calculated using the formula \( KE = \frac{1}{2} mv^2 \), where \( m \) is mass and \( v \) is velocity. Since both balls are moving at the same speed, the ball with greater mass (the tennis ball) will have greater kinetic energy.
