Type: MCQ-numerical-Hard-Class 11
A ball of mass 0.5 kg is released from a height of 10 meters. What is the speed of the ball just before it hits the ground?
A
14 m/s
B
10 m/s
C
20 m/s
D
7 m/s
Correct Answer
Option A
Detailed Explanation
According to the kinematic relation v^2 = 2gh, substituting g = 9.8 m/s^2 and h = 10 m, we find v = sqrt(2 * 9.8 * 10) = 14 m/s.
