A tennis ball weighing 0.5 kg is served across the tennis court and hits at a velocity of 3m/s. A bowling ball weighing 7 kg is rolled down an alley at 2 m/s. Which object has more kinetic energy? Explain your answer using scientific evidence and reasoning.
Make sure to use the formula KE= 1/2 *Mass* Velocity*Velocity to calculate the Kinetic energy for both the objects.
Check to see which of the ball has more kinetic energy.
Next , explain using the calculation which ball has more Kinetic energy and why?
