Practice question
Question
A ball is dropped from a height h and hits the ground with a speed of 29.4m/s after 1.5s of fall. What is the value of g at that location?
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 1.5 s. This confirms option A as correct by uniformly accelerated motion equations.
