1.7 m/s

Explanation:

Relevant Data provided as per the question below:-

Radius = 15.0 cm

Time = 0.56 s.

Based on the above information

The computation of the speed of the object is shown below:-

$Velocity = \frac{2\times \pi \times Radius}{Time}$

$Velocity = \frac{2\times \frac{22}{7} \times 0.15}{0.56}$

$= \frac{0.942857}{0.56}$

= 1.683 m/s

= 1.7 m/s

Therefore for computing the speed of the object or velocity we simply applied the above formula by considering the pi and all other given data
