An object is travelling on a circular track. If the radius of the track is 5.5
m and the period is 18 seconds, what's the objects velocity? (Round to
the nearest hundredth)

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

a, c, d, e are all applying about success strategies.

well, you would divide 135 by 33 to get your answer. then that is how many seconds it would take. boardman should fly about 132 m or 4.090909090909091 seconds.
