Question

select the correct answer.
what is the average velocity of the particle from rest to 15 seconds?
displacement (m)
time (s)
a. 1.1 meters/second
b. 1.2 meters/second
c. 1.3 meters/second
d. 1.4 meters/second

Explanation:

Step1: Identify total displacement

From the graph, at \(t=15\) s, displacement \(d = 20\) m.

Step2: Identify total time

Total time \(t = 15\) s (starts from rest, \(t=0\)).

Step3: Calculate average velocity

Average velocity formula: \(v_{avg} = \frac{\text{Total Displacement}}{\text{Total Time}}\)
\(v_{avg} = \frac{20}{15} \approx 1.3\) meters/second

Answer:

C. 1.3 meters/second
