A vertical spring with force constant k ...

A vertical spring with force constant `k` is fixed on a table. A ball of mass `m` at a height `h` above the free upper end of the spring falls vertically on the spring , so that the spring is compressed by a distance `d`. The net work done in the process is

A

`mg(h+d)-1/2kd^2`

B

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

C

`mg(h-d)+1/2kd^2`

D

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