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.
