Question 1: An aircraft moves at a velocity of 156 km/hr [N60W] changed to a velocity of 65.0 km/hr [N15E] in 15 mins. Determine the acceleration of this aircraft. (K:2, A:2, C:2) Question 2: A swimmer wants to cross a 4.5 km river. In still water she was able to swim at 3.0 km/hr. The river is flowing at 1.0 km/hr. Determine: (C:2 for diagrams) A. What is her velocity relative to the shore? B. How far downstream will she land? (K:1, A:2) C. If she would like to arrive directly across the river, what direction should she make and how long will take her to across the river in this situation? (1:2) (K:1, 1:3) Question 3: A cruise ship is leaving Lisbon at a velocity of 25.0 km/hr [35 S of W] on a ocean, heading for Canada. The ocean current is moving at 4.50 km/hr [20 N of E]. Determine the resultant velocity relative to Lisbon. (K:2, A:2, C:2) Question 4: A soccer ball was kicked from a 45.0 m high cliff with a velocity of 20.0 m/s, 30.0 from horizontal. A. What would be the time of flight of this soccer ball? B. Determine the impact velocity. (K:2, 1:2, A:2)
