PART C: Multiple Choice (1 mark each: total 19 marks) 1. An airplane travelling due west experiences a uniform acceleration due to a wind directed south. Eventually, its velocity (K) is directed south may be directed south is directed south-west is directed west may be directed west F951???\" 2. A boat, while crossing a river, points directly north toward the opposite shore for the entire trip. The current is perpendicular to the direction the boat is pointing in. The time it will take to cross will be (K) more than if the boat was pointing at an angle somewhat upstream more than if the boat was pointing at an angle somewhat downstream dependent on the strength of the current the same regardless of the current impossible to predict without more information SUP-99'5\" 3. In a competition to see who could throw a football the furthest (if wind resistance can be ignored), one should release the ball at an angle of: (K) 45 less than 450 greater than 450 90 00 F951???\
