A stone is dropped from rest. What is the distance covered in the 2nd second of its fall? (Take g\=10m/s2)
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 15 m. This confirms option D as correct by uniformly accelerated motion equations.
