Question

A body is released from a great height and falls freely towards the earth. Another body is released from the same height exactly one second later. The separation between the two bodies, two seconds after the release of the second body is

• A. 4.9 m
• B. 9.8 m
• C. 19.6 m
• D. 24.5 m

Answer 1

The correct option is D

24.5 m

The first body would have travelled for 3s. Since both of them start from rest,the

separation between the two bodies, two seconds after the release of second body is

$x=\frac{1}{2}\times 9.8\left[\right(3{)}^2-\left(2{)}^2\right]=24.5m$
