NEET Physics Potential Energy MCQ Question
Type: MCQ-numerical-Hard-Class 11
A ball of mass 0.5 kg is dropped from a height of 10 m. Neglecting air resistance, what is its speed just before it hits the ground?
A
10 m/s
B
14 m/s
C
20 m/s
D
28 m/s
Correct Answer
Option B
Detailed Explanation
Using the equation v^2 = 2gh, where g = 9.8 m/s^2 and h = 10 m, the speed v is calculated as v = sqrt(2 * 9.8 * 10) = 14 m/s.
