Astudent is performing an investigation of energy transformation. she places a 500-gram car at point x on a wooden racetrack.

what would be the most likely outcome of a 700-gram car being placed on the racetrack at starting point x?

a. it would have more kinetic energy at the start, resulting in greater potential energy at the bottom of the track.

b. it would have more potential energy at the start, resulting in greater kinetic energy at the bottom of the track.

c. it would have less kinetic energy at the start, resulting in less potential energy at the bottom of the track.

d. it would have less potential energy at the start, resulting in less kinetic energy at the bottom of the track.
