A beetle runs an erratic pattern on a square kitchen table that is 1.5 m on a side. The sides are arranged along the directions north/south and east/west. It begins at the southwest corner and travels east along one side to the adjacent corner in 20.0 s. It then turns north and reaches the northeast corner 12.5 s later. What is the magnitude of the beetle's average velocity for the whole trip?
A) 0.092 m/s
B) 0.098 m/s
C) 0.065 m/s
D) 0.033 m/s

Question

Quizplus · Accepted Answer

The beetle covers a total distance of 3 meters (1.5m + 1.5m) in a total time of 32.5 seconds (20s + 12.5s). Therefore, the average velocity is:

Average Velocity = Total Distance ÷ Total Time

Average Velocity = 3m ÷ 32.5s

Average Velocity ≈ 0.065 m/s

Therefore, the answer is choice C, 0.065 m/s.
