A body released from a great height falls freely towards the earth. Another body is released from the same height exactly a second later. Then the separation between two bodies, 2 ~s after the release of the second body is nearly

Step-by-step solution

Let the first body fall through a height h₁ during 3 ~s h₁= 1 2 g(3)^2= 9 2 g and the second body falls through a height h₂ during 2 ~s aligned & h₂= 1 2 g(2)^2= 4 2 g h₁-h₂ & = 9 2 g- 4 2 g= 5 2 g=25 ~m aligned
