A block of mass `m` sits at rest on a frictionless table in a rail car that is moving with speed `v_(c)` along a straight horizontal track (fig.) A person riding in the car pushes on the block with a net horizontal force `F` for a time `t` in the direction of the car's motion.

What is the final speed of the block according to a person in the car ?
