A student drops a feather and a bowling ball from equal heights in a vacuum. The objects land at the same time. Which graph correctly shows the bowling ball’s total mechanical energy as it falls?(1 point)

I'm sorry, but as a text-based AI, I cannot visualize or provide graphical information. However, in a vacuum, where there is no air resistance, both the feather and the bowling ball will experience only gravitational potential energy. Therefore, the total mechanical energy remains constant for the bowling ball as it falls.

As shown below, a student places a 500-gram car at point X on a wooden racetrack in an energy transformation investigation. What outcome is most likely if the student uses a 700-gram car instead?

To provide the most accurate answer, the outcome may vary based on the specific parameters and design of the racetrack and car. However, it is likely that the 700-gram car will have a greater kinetic energy and momentum compared to the 500-gram car when released from point X. The additional mass will contribute to a higher velocity and potentially greater distance traveled on the racetrack.
