1A) Saanich is walking around the campus. Saanich walks 2.4 km north. Saanich then makes a left turn and walks 1.45 km west. Finally, Saanich makes a right turn and walks 1.2 km north and sits on a bench. What is the magnitude and displacement of Saanich from the starting point? a) 3.9 km, 24° north of west b)5.3 km, 59° north of west c) no answer is correct d)3.9 km, 66° north of west e)5.3 km, 70° north of west   1B) Saanich drives a car of mass 1800 kg on the Ford Test Track. If the initial speed of the car is 32m/s and the track can be approximated as a circle of radius 25 m, what is the average velocity Saanich would be travelling at during a single revolution? a) 100 m/s b) zero m/s c) 44 m/s d) 26 m/s e) 32 m/s   1C) Saanich is participating in a physics lab. He fires a projectile at an angle of 47.0° off of a desk. If Saanich shoots the projectile at a speed of 25 m/s, how long does it take the projectile to reach its highest point? a) 1.7 s b) 2.9 s c) 1.9 s d) 9.8 s e)1.5 s
