The answer is Noah.
Since net force = mass x acceleration, we just multiple the mass of the block by how fast each strongman is pushing their block.
Jordan is pushing a 90 kg block at a rate of 1.2 m/s to the second power. 1.2 to the second power is 1.44, and 1.44 x 90 = 129.6.
Noah is pushing a 75 kg block at a rate of 1.5 m/s to the second power. 1.5 to the second power is 2.25, and 2.25 x 75 = 168.75.
168.75 > 129.6.
