Which object has the most kinetic energy? (Hint: How is kinetic energy related to mass and velocity?) Answer
Object A: 100 kg (2 m/sec)
Object B: 40 kg (4 m/sec)
Object C: 10 kg (5 m/sec)
Object D: 500 kg (1 m/sec) Which object has the most kinetic energy? (Hint: How is kinetic energy related to mass and velocity?) Which object has the most kinetic energy? (Hint: How is kinetic energy related to mass and velocity?) Object A: 100 kg (2 m/sec) Object B: 40 kg (4 m/sec) Object C: 10 kg (5 m/sec) Object D: 500 kg (1 m/sec)
Object A: 100 kg (2 m/sec)
Object B: 40 kg (4 m/sec)
Object C: 10 kg (5 m/sec)
Object D: 500 kg (1 m/sec)

Explanation / Answer

Object C: 10 kg (5 m/sec)

Kinetic energy is the energy of motion or energy being used. And to solve this problem, you would have to put each truck as a ratio between weight and velocity. However, ratios were not neccesary here due to the information provided.
If the 4 ton truck has the same Kinetic energy as the 3 and 1 ton trucks at the speed it is going, the 6 ton truck has the most due to the fact that it is much heavier and has less of a speed decrease than it should have to be having the same Kinetic energy as the others.
