Kinematics Question 339
Question: In 1.0 s, a particle goes from point A to point B, moving in a semicircle of radius 1.0 m . The magnitude of the average velocity is
Options:
A) $ 3.14m/s $
B) $ 2.0m/s $
C) $ 1.0m/s $
D) Zero
Show Answer
Answer:
Correct Answer: B
Solution:
$ |\text{ Averagevelocity }|\text{ = }\frac{|\text{ displacement }|}{time} $
$ \text{=}\frac{2r}{t}\text{=2 }\times\frac{1}{1}\text{=2 m/s}\text{.} $
