Question

If a particle goes from point A to point B in $1$ s moving in a semicircle(See figure). The magnitude of the average velocity is:

• A. 3.14 $m{s}^{-1}$
• B. 2 $m{s}^{-1}$
• C. 1 $m{s}^{-1}$
• D. zero

Answer 1

The correct option is B 2 $m{s}^{-1}$

Here average velocity
$=\frac{displacementAB}{time}$
$=\frac{2}{1}=2m{s}^{-1}$
