A body released from a great height falls freely toward earth. Another body is released from the same height exactly one second later. What is the separation between both the bodies two seconds after the release of the second body?

Answer:

Distance covered by first body in 3s \[=\frac{1}{2}\times 9.8\times {{(3)}^{2}}=44.1\,m\] Distance covered by second body in 2s \[=\frac{1}{2}\times 9.8\times {{(2)}^{2}}=19.6\,\,m\] Separation of two bodies 2 seconds after the release of second body \[=44.1-19.6=24.5\,m\]
