NEET Physics Potential Energy MCQ Question
Type: MCQ-numerical-Easy-Class 11
A ball of mass 0.5 kg is dropped from a height of 10 meters. What is its speed just before hitting the ground? (Use g = 10 m/s²)
A
14.1 m/s
B
10 m/s
C
20 m/s
D
12.5 m/s
Correct Answer
Option A
Detailed Explanation
Using the equation v² = 2gh, where h = 10 m and g = 10 m/s², we get v² = 2 * 10 * 10 = 200. Therefore, v = √200 = 14.1 m/s.
