Write the answer to this question. energy is measured in units called joules(j). suppose a roller coaster car starts with 78,000 j of potential energy. in a few seconds, it converts two-thirds of this energy into kinetic energy. as it takes a curve, the car doubles its kinetic energy. how much mechanical energy does the car now have?
