Final answer:
The form of energy that was present after the Gravity Racers made it to the carpet is kinetic energy.
Step-by-step explanation:
The form of energy that was present after the Gravity Racers made it to the carpet is kinetic energy.
As the racers went down the slope, the gravitational potential energy was converted into kinetic energy. Kinetic energy is the energy possessed by an object due to its motion. When the racers made it to the carpet, they were still in motion, so their energy was in the form of kinetic energy.
For example, if you drop a ball from a height, it will gain kinetic energy as it speeds up due to the conversion of its potential energy into kinetic energy.
