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.

How much did `K.E` of the block change according to the person in the car ?
