A student 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?
Group of answer choices

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

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

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

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

Respuesta :

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

Answer: Option A.

Explanation:

The car at the race track will accelerate at point X. It will have more kinetic energy at the start because the car is at the slope and with time it will result in greater potential energy at the bottom.

As we go down towards the bottom of the track, the kinetic energy will get converted into potential energy because here the body starts coming at rest and is not moving.
