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.

Respuesta :

ke prop to v^2

ke1/v1^2=ke2/v2^2

400/50x50=joules/100x100

400x2x2

1600j

Answer:

I just took the test and it's 1,600 and quadruple.
