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. `3.14 ms^(-1)`
B. `2.0 ms^(-1)`
C. `1.0 ms^(-1)`
D. zero

Answer

B

Explanation

`|"Average velocity"| = (|"Displacement"|)/("Time")`
`= (2r)/(t) = 2 xx (1)/(1) = 2 ms^(-1)`
