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×speed2Show your working.
