An automated guided vehicle (AGV) in a factory warehouse moves along a flat, straight track of length 45 m.
The total mass of the AGV and its payload is 250 kg.
To maintain a constant speed against a resisting force, the AGV's motor exerts a constant forward driving force of 60 N.
The AGV travels along the track with a constant velocity of 1.8 m s-1.
Calculate the kinetic energy of the AGV and its payload.
