Answer 1

To determine the time it takes for Rock 2 to fall, we can use the principles of physics related to free fall. The time it takes for an object to fall freely from a height (assuming negligible air resistance) is independent of its mass.

Since Rock 1 takes 4.0 seconds to fall from a height of 78.4 meters, Rock 2, which has a greater mass but falls the same height under the same conditions, will also take the same amount of time.

Thus, Rock 2 will take:

4.0 seconds.

The correct response is 4.0 seconds.
