Complete the paragraph to describe the relationship between kinetic energy and braking distance. Use. A car moves at a speed of 50 kilometers/hour. Its kinetic energy is 400 joules. If the same car moves at a speed of 100 kilometers/hour, then its kinetic energy will be joules. The braking distance at the faster speed is the braking distance at the slower speed.

    Answer:A car moves at a speed of 50 kilometers/hour. Its kinetic energy is 400 joules. If the same car moves at a speed of 100 kilometers/hour, then its kinetic energy will be 1,600 joules. The braking distance at the faster speed is double the braking distance at the slower speed.
