Based on the data, rock 2 has a mass of 25 kg and falls from a height of 78.4 m. The time it takes for a rock to fall is determined by the height of the fall and the acceleration due to gravity.
Using the equation, h = 0.5 * g * t^2, where h is the height, g is the acceleration due to gravity, and t is the time, we can solve for t:
78.4 = 0.5 * 9.8 * t^2
8 = t^2
t = √8
t ≈ 2.83
Therefore, it will take approximately 2.83 seconds for rock 2 to fall.
