Some kids playing at the park get creative, and they turn a seesaw into a trebuchet – they slide the plank until only 20 cm of its total length of 4 m extends from one side of the fulcrum. While bracing the system in a horizontal position, they place a 0.5 kg cantaloupe on the really long end, and three 25 kg kids sit on the short end (assume at the very end). Once the braces are removed, the kids fall, flinging the cantaloupe. What maximum velocity does the cantaloupe reach? Ignore the mass of the plank.
