1. Ken is driving a race car around a circular track that has a diameter of 70.0 m spins. Ken takes 46.4.2 seconds to make two loops around the track. Determine Ken's acceleration. [4 Marks]

2. An aircraft is travelling at 240 m/s [S60oE] when it encounters some wind causing it to now move at a rate of 210 m/s [W42oS] for 5 minutes. What displacement will the aircraft have during this time interval? (8 marks)

3. A boat that can travel 1.5 m/s in still water is traveling east across a river with the water flowing south at a speed of 1.0 m/s. If the river is 100 m. wide a. What is the velocity of the boat relative to the shore? b. Where will the boat land down stream? [ 4 marks]

4. Refer to the velocity-time graph. considering the segment for t = 1.0 s and t = 2.0 s, Arman says that the graph shows that the object traveled approximately 8.0 m [E] . Karen says that it shows the object traveled approximately 11.0 m [E]. Assess which of these you think is correct. Justify your answer. (2 marks)
