On a merry-go-round, animals at the edge are located 4 times farther from the axis of rotation than the animals near the center. The animals near the center has a rotational speed of 3 RPM and a tangential speed of 2 m/sec.

What is the rotational speed of the animals near the edge?

a 3 RPM
b 12 RPM

12 RPM

Step-by-step explanation:

I would calculate the distance from the edge to the center, and then multiple that by 3RPM with 2 m/sec
