Rock 1 Rock 2 Mass (kg) 2.5 25 Height of Fall (m) 78.4 78.4 Time to Fall (s) 4.0 ? Based on this data, how many seconds will it take rock 2 to fall? (1 point) Responses 1.6 seconds 1.6 seconds 0.4 second 0.4 second 4.0 seconds 4.0 seconds 40 seconds

Answer 1

To determine how long it will take Rock 2 to fall, we can use the following information:

1. Both rocks are falling from the same height (78.4 m).
2. The time taken for Rock 1 to fall (2.5 kg) under the influence of gravity is 4.0 seconds.

According to the principles of physics, the time it takes for an object to fall from a certain height under the influence of gravity is independent of its mass. Therefore, since both rocks are falling through the same height in a vacuum, Rock 2 (25 kg) will also take the same time to fall as Rock 1.

Given that Rock 1 takes 4.0 seconds to fall, Rock 2 will also take 4.0 seconds to fall.

So the correct response is:

4.0 seconds.
