Question 2

During a test run of a prototype high-speed capsule inside a vacuum transport tube, the kinetic energy of a 120 kg capsule is 216 000 J216\,000\text{ J}216000 J.

Calculate the speed of the capsule during this test.

Use the equation:

kinetic energy=0.5×mass×speed2 \text{kinetic energy} = 0.5 \times \text{mass} \times \text{speed}^2 kinetic energy=0.5×mass×speed2
