Two stones are dropped from a height of 245m, with a 3s interval. What is their separation when the second stone has fal
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 165 m. This confirms option C as correct by uniformly accelerated motion equations.
