Tony wishes to use a canoe to cross to the other side of a river which is 25 m wide. The river is flowing at 5 m/min and Tony can paddle at 15 mlmin. Round your answers to the nearest tenth where possible. a) In what direction should Tony aim the canoe in order to land at a point directly opposite her starting point? How long will it take to make this crossing? [2 marks] b) If Tony's goal is a dock which is 10 m downstream from a point directly opposite his starting point, in what direction should he aim his canoe? [3 marks] a) The amount of work done by a 24 N force in moving an object from NE, a) to B(17,12) is 173.066. J. The force is applied at a 60 angle to AB at A. Assume the distance moved is in meters. Find the valueis) of a. [3 marks] _. _. 1 .' [2 marks] a) Consider the plane with a scalar equation 4x - 2y + z - 19 = 0. Find the point of intersection of this plane with the line passing through the points A(1, -6, -5) and B(3, -3, -3). [3 marks] b) Where does the line with the vector equation [x, y, z] = [6, 7, -8] + t[-2, 4, 1] intersect the xy-plane? [2 marks]
