Mixed Motion ConceptsHardQuestion 5254
Question
A body falling freely from height H has velocity v at height H/4 from ground. Then v is:
- A√(gH/2)
- B√(gH)
- C√(3gH/2)Correct
- D√(3gH/4)
Correct answer
√(3gH/2)
Explanation
Body falls from H to H/4, covering 3H/4. v² = 2g(3H/4) = 3gH/2 → v = √(3gH/2).
