\fQuestion 17 (4 points) Using the sine and/or cosine law, sindA __ sin B a b c =a+b% - 2ab cosC Find the magnitude of the resultant of these two vectors: 14 km at a bearing of 10 11 km at a bearing of 160 Show your mathematical work, but you do not need to include a diagram. *Note that your calculator should probably be changed to degree mode for this section of the final test. \fQuestion 12 (3 points) An aircraft is flying at 335 km/h on a bearing of S 40 W. The wind is blowing at 85 km/h from a bearing of S 60 W. Determine the actual ground speed and the direction of the aircraft. You do not need to include a diagram, but it may be helpful to draw one for your own reference. *Sine and cosine law are also found in a different question in this section, so if you need a reference, look for those. "MNote that the question states "from a bearing of..." This means the direction of the wind is actually the opposite of that. Question 20 (2 points) Bryan is pushing a cart up a 12 m loading ramp with a constant force. The ramp is at an angle of 11 with the horizontal. - Given that work done in Joules is f * 8, where fis the force in Newtons and s is the displacement in metres, and that Bryan did 90 J of work, what amount of force did he use
