STANDARD Physics Free Fall MCQ Question
From a building, two balls A and B are thrown such that A is thrown upwards and B downwards with the same speed (both vertically). If vₐ and vᵦ are their respective velocities on reaching the ground then,
vᵦ > vₐ
vₐ = vᵦ
vₐ > vᵦ
their velocities depend on their masses.
Correct Answer
Detailed Explanation
Both balls A and B are thrown with the same speed u, but in opposite directions. When they reach the ground, their velocities are given by vₐ = √(u² + 2gh) and vᵦ = √(u² + 2gh), which are equal. Thus, vₐ = vᵦ.
