HEEY GUYS!!

today in physics class ms.kozoriz "section 5.1: graphing motion in one dimension" and "section 4.1: properties of vectors". Here are the answers
Section 5.1: Graphing Motion in One Dimension

1. Position(y-axis) Time(x-axis)
2. At the same position
3. Objects at rest
4. Not a finite period of time
5. 0's
6. A
   
7. D
8. B
9. B
10. D
11. C
12. arrows going to the right that are the same distance apart
13. two dots separated from each other
    
14. arrows going to the left that are the same distance apart
    
15. False (4 quantities)
16. True
17. False (d represents the the position at any time)
18. True
19. True

Table One
Segment v a - 0.25km/min
v b - 0
v c - 0.4km/min

Δt a - 10min
Δt b - 7min
Δt c - 13min

Δd a - 2.5km
Δd b - o
Δd c - 5.2km

Table Two
Δt = 30min
distance ran = 7.7 km
displacement = 17.7
average velocity = 0.26 km/min


Section 4.1: Properties of Vectors

1. 6km (E)
2. 6km (N)
3. 6km (NW)
4. 4km (N)
5. 3km (W)
6. 5km (SE)
7. 4m (SW)
8. 12km (E)
9. 20m (SE)
10. 400m (W)
11. b) d=2.0 km north
12. d) d=2.0 km
13. H,F,B
14. B,F,G,I
15. B,F
16. True
17. False (protractor)
18. False (tail)
19. True
20. False

Ms. Kozoriz also taught us something about adding vectors. Here it is if you guys missed it















And for the people that was away, dont forget to hand in the "appendix 3.8: inter pretending position time graph which was due today. and we also received 3 sheets called "section 4.2: components of vectors, Simple Vectors, and a crossword puzzle. so dont forget to pick those up.
