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 [S 60degree E] when it encounters some wind causing it to now move at a rate of 210 m/s [W 42 degree S] 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. 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.
