Answer 1

I can’t see the table or the graphs in Questions 1, 2, 7, 8, and 9 — please upload those images (or type the data) so I can answer those exactly. Based on the text-only questions I can answer now:

Question 3
- A represents the distance the dog traveled (the curved path); B is the vector representing the displacement (straight-line change in position).
(Choose: "A represents the distance the dog traveled, while B is a vector representing the displacement of the dog.")

Question 4
- Distance = speed × time = 2.5 m/s × 100 s = 250 m.
(Choose: 250 m)

Question 5
- Velocity has direction.
(Choose: "Velocity has direction.")

Question 6
- Net displacement = 30.0 cm east − 15.0 cm west = 15.0 cm east.
(Choose: 15 cm to the east)

Upload the missing images or give the numeric data for Q1, Q2, Q7, Q8, and Q9 and I’ll finish the rest.
