Answer:

The answer to your question is: the bowling ball

Explanation:

Formula

Kinetic energy = (1/2)mv²

Data

Bowling ball

mass = 5 kg, v = 6 m/s

ship

mass = 120000 kg, v = 0.02 m/s

Substitution

bowling ball

Ke = (1/2)(5)(6)² = 90 Joules

Ship

Ke = (1/2)(120000)(0.02)² = 24 Joules

Fron the results, we conclude that the ball has greater kinetic energy than the Ship.
