Question

The motion of an insect on the floor is shown on a number line. It started its journey from point O moving towards A and finished at point B in a time span of 1 minute. What is its average velocity during the journey?

• A. 1 m/s
• B. 1 m/s
• C. -0.5 m/s
• D. 0.5 m/s

Answer 1

The correct option is C -0.5 m/s

Displacement that depends on the endpoints, s = -30 m
Time elapsed, t = 1 min = 60 s
$\text{Average velocity}\left(v_{av}\right),v_{av}=s/t=-30/60=-0.5m/s$
