Modeling circular motion, picture attached to the question. the boat is traveling at a rate of 1 meter per second. how long does it take the barnacle to get back to its starting point?

Step-by-step explanation:

The circumference of a circle of radius r is given by

... C = 2πr

When r = 1 m, then

... C = 2π(1 m) = 2π m

The relation between time, distance, and speed is ...

... time = distance/speed

... time = (2π m)/(1 m/s) = 2π s

Comment on the scenario

We have a hard time imagining what sort of scenario this is modeling, as it appears the "boat" is rotating in such a way as to place the barnacle above and below the water level. This problem may be nonsensical, but at least it is workable. (Some aren't.)
