A particle of mass m , initially at rest...

A particle of mass `m` , initially at rest , is acted upon by a variable force `F` for a brief interval of time `T`. It begins to move with a velocity `u` after the force stops acting . `F` is shown in the graph as a function of time. The curve is a semicircle.

A

`u=(piF_(0)^(2))/(2m)`

B

`u=(piT^(2))/(8m)`

C

`u=(piF_(0)T)/(4m)`

D

`u=(F_(0)T)/(2m)`
