To determine how long it will take rock 2 (mass = 25 kg, height = 78.4 m) to fall, we can use the information provided for rock 1 (mass = 2.5 kg, height = 78.4 m, time to fall = 4.0 s) to find a pattern.
Given that both rocks are falling from the same height (78.4 m), the mass of the rocks does not affect the time they take to fall in a vacuum (ignoring air resistance). Since both rocks fall the same distance (78.4 m), we can conclude that:
- Rock 1 takes 4.0 seconds to fall 78.4 m.
- Rock 2, falling the same distance, will also take the same amount of time to fall.
Thus, rock 2 will also take **4.0 seconds** to fall.
So, the correct response is **4.0 seconds**.
