A boat leaves the dock at t = 0 and heads out into a lake with an acceleration of 2.1 m/s2 î. A strong wind is pushing the boat, giving it an additional velocity of 2.1 m/s î + 2.2 m/s ĵ. (Assume the boat is at the origin at t = 0. Express your answers in vector form.) (a) What is the velocity of the boat (in m/s) at t = 10 s?
