Question

As shown below, an object with a mass of 5 kg is moving at a speed of 10 m/s. Another object with a mass of 10 kg is moving at a speed of 5 m/s.

Which of the objects has higher kinetic energy

Answer 1

[AI-generated answer — Bot GPT 3.5]

To determine which object has higher kinetic energy, we can use the formula for kinetic energy:

Kinetic energy (KE) = (1/2) * mass * velocity^2

For the first object with a mass of 5 kg and a velocity of 10 m/s:

KE1 = (1/2) * 5 kg * (10 m/s)^2 = 250 Joules

For the second object with a mass of 10 kg and a velocity of 5 m/s:

KE2 = (1/2) * 10 kg * (5 m/s)^2 = 125 Joules

Therefore, the first object with a mass of 5 kg and a speed of 10 m/s has higher kinetic energy (250 Joules) compared to the second object with a mass of 10 kg and a speed of 5 m/s (125 Joules).
