Please help. 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.

The bowling ball has more kinetic energy than the tennis ball

Explanation:

Using the formula 1/2 mass × acceleration we found that the tennis ball had a kinetic energy of 0.75 while the bowling ball had a kinetic energy of 10.5 hence the bowling ball has the ability to do more work
