In a water-tank test involving the launching of a small model boat, the model’s initial horizontal velocity is 6 m/s and its horizontal acceleration varies linearly from –12 m/s2 at t = 0 to –2 m/s2at t = formula120.mml and then remains equal to –2 m/s2 until t = 1.4 s. knowing that v = 2.6 m/s when t = formula120.mml, determine the value of formula120.mml and the velocity and the position of the model at t =1.4 s. (round the final answers to two decimal places.)
