1. It will take 0.45 s for the bowling ball to fall 1 m
2. it will take 0.45 s for the ping pong ball to fall 1 m
Data obtained from the question
From the question given above, the following data were obtained:
- Height (h) = 1 m
- Acceleration due to gravity (g) = 9.8 m/s²
- Time (t) =?
How to determine the time taken to fall
The time taken for the bowling ball to fall can be obtained as illustrated below:
h = ½gt²
1 = ½ × 9.8 × t²
1 = 4.9 × t²
Divide both side by 4.9
t² = 1 / 4.9
Take the square root of both side
t = √(1 / 4.9)
t = 0.45 s
Thus, it will take 0.45 s for the bowling ball to fall.
Considering the ping pong ball, it will also take 0.45 s to fall 1 m since the same gravity is acting on it
