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)/(2)kd^(2)`

B

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

C

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

D
