The graph below plots the position of a dog on a sidewalk, relative to a fire hydrant. d (m) [E] vs t (s) 15 d (m) [E] 0 5 10 -5 5 10 15 20 20 t(s) 1. Tell the story of the dog's motion. Be as detailed as you can. 2. Where is the dog at 3s, 7s, 17s? 10 m [E], 6 m [E], 1 m [W] 3. When is the dog right beside the fire hydrant? 4. Determine the velocity of the dog in each section. 0-5s0 m/s, 5-12s 0.86 m/s, 12-14s 0 m/s, 14-20s 0.33 [W] 5. For the entire motion (0 - 20s), what is the dog's distance travelled? What is her displacement? Distance: 30 m Displacement: 2 - 10 = 8 m [W] 6. For the entire motion, what is the dog's average speed? What is her average velocity? Average Speed: 30m/20s= 1.5m/s Average velocity: 8m/20= 0.4 m/s [W] 7. When is the dog west of the fire hydrant?
