Answer 1

$\huge{\fcolorbox{cyan}{black}{\red{ANSWER:-}}}$

Two bodies, A (of mass 1 kg) and B (of mass 3 kg) are dropped from heights of 16 m and 25 m, respectively. The ratio of the time taken by them to reach the ground is. 5/4.

Hope that helps..!!

Answer 2

Solution :

➝As the body was dropped from a certain height,there

initial velocities are Zero i.e. U = 0

➝ H1 = 36 & H2 = 49

➝ t1 / t2 = √H1 / √ H2

➝ √36/√49

➝ 6/7

➝Option A is the correct answer !
