A feather in a bowling ball Rh dropped from an equal hot in a vacuum and land at the same time which graph shows the total mechanical energy of the bowling ball as it falls

Answer 1

Since the feather and the bowling ball are dropped from the same height, they will experience the same change in gravitational potential energy (which is converted to kinetic energy as they fall). Therefore, the total mechanical energy of the bowling ball will remain constant throughout the fall since there is no external work done on the system.

Graph (b) would best depict the total mechanical energy of the bowling ball as it falls. It would show a horizontal line at a constant value, representing the constant total mechanical energy of the system.
