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)
As the feather and the bowling ball are dropped from equal heights in a vacuum, they experience the same gravitational force and acceleration.
Therefore, the bowling ball's total mechanical energy will remain constant throughout the fall, as mechanical energy is conserved in the absence of external forces like air resistance.
The correct graph would show the bowling ball's total mechanical energy staying constant as it falls.
