An object is moving in a circle of radius 100 m with a constant speed of `31.4 m//s` . What is its average speed for one complete revolution
A
Zero
B
`31.4 m//s`
C
`3.14 m//s`
D
`sqrt(2)xx3.14 m//s`
Text Solution
Verified by Experts
The correct Answer is:
B
The object is moving with a constant speed . Hence his average speed = instantaneous speed `=31.4 m//s` However its average velocity is zero.
