NEET Physics (general) MCQ Question
Type: MCQ-numerical-Easy-Class 11
If a ball is dropped from height H and reaches a speed v_f at ground level, what is the relation between v_f and H?
A
v_f = sqrt(2gH)
B
v_f = 2gH
C
v_f = gH^2
D
v_f = 2gH^2
Correct Answer
Option A
Detailed Explanation
Using the conservation of mechanical energy, E_H = E_0, we have (1/2)mv_f^2 = mgH, leading to v_f = sqrt(2gH).
