A) \[3.14\,\,m/s\]
B) \[2.0\,\,m/s\]
C) \[1.0\text{ }m/s\]
D) Zero
Correct Answer: B
Solution :
\[\text{ }\!\!|\!\!\text{ Averagevelocity }\!\!|\!\!\text{ = }\frac{\text{ }\!\!|\!\!\text{ displacement }\!\!|\!\!\text{ }}{\text{time}}\] \[\text{=}\frac{\text{2r}}{\text{t}}\text{=2 }\!\!\times\!\!\text{ }\frac{\text{1}}{\text{1}}\text{=2 m/s}\text{.}\]
