Two bodies, A (of mass 1 kg) and B (of mass 3 kg), are dropped

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

Let t₁ & t₂ be the time taken by A and
B respectively to reach the ground then from the formula,

h =	1	gt²
	2

For first body, 16 =	1	gt₁²
	2

For second body, 25 =	1	gt₂²
	2

∴	16	=	t₁²	⇒	t₁	=	4
	25		t₂²		t₂		5
