Answer:
1.92 m/s
Explanation:
Velocity is defined as the distance moved per unit time with consideration of the direction. The direction aspect differentiates speed from velocity since for speed, we don't need to consider the direction.
Distance moved for circular path is equal to its circumference and the circumference is given by where r is the radius and substituting
for d then
Substituting 5.5 m for r and 18 s for t then
To the nearest hundredth, the velocity is 1.92 m/s
