Two balls are dropped from a height of 125m, 2s apart. How long after the second ball is released do they meet if the fi
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 5 s. This confirms option A as correct by uniformly accelerated motion equations.
