NEET Physics Potential Energy MCQ Question
Type: MCQ-numerical-Medium-Class 11
A ball of mass 2 kg is released from a height of 5 meters. What is its speed just before it hits the ground?
A
10 m/s
B
9.8 m/s
C
14 m/s
D
20 m/s
Correct Answer
Option A
Detailed Explanation
Using the equation v^2 = 2gh, we find v = sqrt(2 * 9.8 * 5) ≈ 10 m/s, showing the potential energy converts to kinetic energy.
