Use the table of data for two falling rocks to answer the question.
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?

To find the time it will take for rock 2 to fall, we can use the equation:
Time = square root(2 * height of fall / acceleration due to gravity)
For both rocks, the height of fall is given as 78.4 m. The acceleration due to gravity is approximately 9.8 m/s^2.
For rock 1:
Time = square root(2 * 78.4 / 9.8) = 4.0 seconds.
Therefore, it will also take rock 2 4.0 seconds to fall.
The correct response is: 4.0 seconds
