Question

Rohit completes a semi circular path of radius R in 10 seconds. Calculate average speed and average velocity in ms^-1.

$\frac{2 πR}{10}, \frac{2 R}{10}$
$\frac{πR}{10}, \frac{R}{10}$
$\frac{- R}{10}, \frac{2 R}{10}$
$\frac{2 πR}{10}, \frac{R}{10}$

The correct answer is: $fraction numerator negative R over denominator 10 end fraction comma fraction numerator 2 R over denominator 10 end fraction$
