The masses, volumes, and speeds of several objects are shown. Which object has the greatest kinetic energy?(1 point)Responsesmass = 2 kg, volume = 10,000 cm3, speed = 5 m/smass = 2 kg, volume = 10,000 cm 3 , speed = 5 m/smass = 5 kg, volume = 2,000 cm3, speed = 10 m/smass = 5 kg, volume = 2,000 cm 3 , speed = 10 m/smass = 5 kg, volume = 5,000 cm3, speed = 5 m/smass = 5 kg, volume = 5,000 cm 3 , speed = 5 m/smass = 2 kg, volume = 5,000 cm3, speed = 10 m/s

Answer 1

To calculate the kinetic energy, we can use the formula:

Kinetic energy = 0.5 * mass * speed^2

Using this formula, let's calculate the kinetic energy for each object:

1. Kinetic energy = 0.5 * 2 kg * (5 m/s)^2 = 0.5 * 2 * 25 = 25 J
2. Kinetic energy = 0.5 * 2 kg * (5 m/s)^2 = 0.5 * 2 * 25 = 25 J
3. Kinetic energy = 0.5 * 5 kg * (10 m/s)^2 = 0.5 * 5 * 100 = 250 J
4. Kinetic energy = 0.5 * 5 kg * (10 m/s)^2 = 0.5 * 5 * 100 = 250 J
5. Kinetic energy = 0.5 * 5 kg * (5 m/s)^2 = 0.5 * 5 * 25 = 62.5 J
6. Kinetic energy = 0.5 * 5 kg * (5 m/s)^2 = 0.5 * 5 * 25 = 62.5 J
7. Kinetic energy = 0.5 * 2 kg * (10 m/s)^2 = 0.5 * 2 * 100 = 100 J

Therefore, the object with the greatest kinetic energy is the one with a mass of 5 kg, a volume of 2,000 cm3, and a speed of 10 m/s.
