Karel and Aleš have one homogeneous brick each. The bricks have cuboid shapes with edge lengths a×a×2a, where a = 5 cm. The mass of each brick is m = 1 kg. Karel puts his brick down and starts flipping it in one direction always about the shorter edge (looking from the side, the longer edge and the shorter edge alternate in touching the ground), until the brick crosses a distance d = 150 cm. Aleš is also flipping his brick until it crosses the distance d, but he is flipping it about the longer edges only (only the square base of the cuboid is ever visible from the side). The bricks do not slip and collisions with the ground are inelastic. How much more work will Karel perform? The acceleration due to gravity is g = 9.81 m·s⁻². Mirek was evaluating the others' performances.
