The time taken for the stone to reach the ground is 7 s
Data obtained from the question
- Height (h) = 245 m
- Acceleration due to gravity (g) = 10 m/s²
How to determine the time
The time taken for the stone to reach the ground can be obtained as follow:
h = ½gt²
245 = ½ × 10 × t²
245 = 5 × t²
Divide both side by 5
t² = 245 / 5
t² = 49
Take the square root of both side
t = √49
t = 7 s
Thus, it will take the stone 7 s to reach the ground.
