13. Two bodies A and B of mass 1 kg
and 2 kg, respectively, are dropper
near the earth's surface. Let the
acceleration of A and B be al and a2
respectively, then

Hey Mate..!
Step-by-step explanation:
I find the answer like this.!
if the question has asked to find the time when they reach the bottom then it will be same for both A and B .
as we know H = 0t + 1/2 gt^2 or t = (2H/g)^2
● Only the impulse of heavier body will be more .
Their acceleratn has to be Same .
if Suppose they are a1 and a2 . Then it may be due to air friction and also air is different in the places where A and B are dropped.
● Therefore in that case consider net acceleration to be a1 and a2 .
a1 = g - (accln due to air friction in atmosphere1)
a2 = g - (accln due to air friction in atmosphere 2)
