How much energy is gained by a box of mass 20 kg when a man raises the box by 0 · 5 m in order to place it inside the bus ? ( g = 10 m s - 2 )

Given: Mass of the box, m = 20 kg . Height in which the box is raised, h = 0 . 5 m . Energy gain while raising the box, E = m g h = 20 × 0 . 5 × 10 = 100 J .
