NEET Physics (general) MCQ Question
Type: MCQ-numerical-Medium-Class 11
A block of mass m is released from a height h above the ground. Assuming no air resistance, what is the speed of the block just before it hits the ground?
A
sqrt(2gh)
B
mg/h
C
2gh
D
gh/m
Correct Answer
Option A
Detailed Explanation
The speed of the block just before it hits the ground is given by the kinematic equation v^2 = 2gh, which simplifies to v = sqrt(2gh). This shows the conversion of gravitational potential energy to kinetic energy.
