1.

In `1.0 s`, a particle goes from point `A` to point `B` , moving in a semicircle of radius `1.0 m ` (see figure ). The magnitude of the average velocity A. `3.14 m//s`B. `2.0 m//s`C. ` 1.0 m//s`D. `Zero`

Answer» Correct Answer - B
`|Average velocity | = (|displacement|)/(time)`
`= ( 2r)/(t) = 2 xx (1)/(1) = 2 m//s `.
