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.)

it has to be b, about 97 percent.

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.

myth. it was once thought that animals, including cats and dogs, could only see in black and white. however, scientists have proven this to be a myth. in all animals, including humans, the perception of colour is determined by the presence of cells in the eye called cone photoreceptors.
