Question

refer to the figure below to answer the following questions. a dog walks from +4 m to +2 m. which of the following statements is true about the dogs motion? question 7 1 pts rank in decreasing order the displacements of objects having the following pairs of average velocity and time of motion. i. v_avg = +2.0 m/s, t = 2.0 s ii. v_avg = +3.0 m/s, t = 2.0 s iii. v_avg = -3.0 m/s, t = 3.0 s

Explanation:

Step1: Determine final position

Dog ends at +2 m (final position).

Step2: Evaluate displacement

Δx = 2 m - 4 m = -2 m (displacement is -2 m, not +2 m).

Step3: Check average velocity

No time given, so Vavg can't be determined.

Step1: Calculate displacement I

Δx_I = 2.0 m/s * 2.0 s = 4.0 m

Step2: Calculate displacement II

Δx_II = 3.0 m/s * 2.0 s = 6.0 m

Step3: Calculate displacement III

Δx_III = -3.0 m/s * 3.0 s = -9.0 m

Step4: Rank displacements

6.0 m > 4.0 m > -9.0 m → II, I, III

Answer:

A. Final position = +2 m (assuming the first option refers to final position)
