A body of mass `m` falls from a height `h` and collides with another body of same mass at rest. After collision, the two bodies combine and move through distance `(d)` till they come to rest. Find the work done against the resistive force.

A

`1/2mg(h + 2d)`

B

`1/2mg(h + 4d)`

C

`1/2mg(h - d)`

D

`1/2mg(h - 2d)`

Text Solution

Verified by Experts

The correct Answer is:
`(2)`
