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

Options

A. `3.14ms^(-1)`
B. `2 ms^(-1)`
C. `1ms^(-1)`
D. zero

Answer

B

Explanation

`"Average velocity"=("Total displacement")/("Total time")=(2m)/(1s)=2ms^(-1)`
