Name: ACI: SPH3U 2D Kinematics 9. A student starts at 1.40 km [E 22S] of ACI. They walk to 3.62 km [S 610W] with respect to AC1 2.00 hours later. a. Find their displacement. b. Calculate their average velocity. 10. Tiffany starts at school which is 2.43 km [W 49GN] of the STC. After biking for 65.0 minutes, she arrives at the 200 which is 11.24 km [N 75E] from the STC. Calculate her average velocity? 11. A plane ying in a triangular pattern ies 150 km [N], then 400 km [E]. a. What third displacement would complete the trip back to the starting point? b. If he completes the entire trip in 3.5 hours, what is the velocity of the entire trip? Page 9 of 24
