How would you measure the speed of a ball rolling on a floor ?

Academic Physics NCERT Class 7

We know $Speed = \frac{Distance}{time}$

Let's say if the ball covers 20m in 5 secs while rolling.

Then:

$Speed = \frac{Distance}{time}= \frac{20}{5}$

= 4m/s.

A batsman hits a cricket ball which then rolls on level ground.After covering a short distance, the ball comes to rest. The ball slows to a stop because$(a)$. the batsman did not hit the ball hard enough.$(b)$. velocity is proportional to the force exerted on the ball.$(c)$. there is a force on the ball opposing the motion.$(d)$. there is no unbalanced force on the ball, so the ball would want to come to rest.
