Ratio of Distance in Consecutive Seconds for Free Fall – Rankers Physics

Equations of Motion: Practice Problem & Solution

The ratio of the distance traveled by a freely falling body in the \(1^{text{st}}\,\text{ }2^{text{nd}}\,\text{ }3^{text{rd}}\) and \(4^{text{th}}\) second: (2022)
1:1:1:1
1:2:3:4
1:4:9:16
1:3:5:7

Solution Explained:

To solve this problem, we apply the core principles of Equations of Motion. Understanding the underlying formula is key to arriving at the correct answer below:

Concept: Galileo's law of odd numbers for free fall.
Formula: Distance in \(n^{text{th}}\) second is \(S_n = \frac{g}{2}(2n - 1)\).
Solution: \(S_1:S_2:S_3:S_4 = (2(1)-1):(2(2)-1):(2(3)-1):(2(4)-1) = 1:3:5:7\).
