STANDARD Physics Free Fall MCQ Question
A body falling freely under gravity passes two points 30 m apart in 1s. From what point above the upper point it began to fall? (Take g = 9.8 m s⁻²).
32.1 m
16.0 m
8.6 m
4.0 m
Correct Answer
Detailed Explanation
Using the equations of motion, we find the time t = 2.56 s for the body to fall 30 m. The initial height above the upper point is calculated using s₁ = 1/2 gt², resulting in 32.1 m.
