Practice question
Question
A stone is dropped from a cliff and takes 5s to hit the ground. What is the height of the cliff? (Take g\=10m/s2)
Explanation
For free fall, s=½gt² and v²=2gh per NCERT. With g=10 m/s², given height or velocity yields time or distance via these equations. Substituting values gives result matching 125 m. This confirms option A as correct by uniformly accelerated motion equations.
