A rotating merry go round has a radius of 30 feet. If it completes one revolution in 20 seconds, find the velocity of the outer edge.
You would need to know something about the size of the tire (its radius, circumfrence, etc.) Knowing this, you can convert revolutions per minute into some form of distance (using the knowledge that 1 revolution = circumference of the tire). The distance can then be converted to kilometers if it is not already. You would also need to convert minutes into hours (knowing that 60 minutes = 1 hour). This should give your speed in kph (kilometers per hour).
A wheel with a diameter of 12 inches will have an angular speed of 560.2 revs per minute.
radius
double of the radius means equal to diameter
1 revolution = 2PI radian. 2 revolutions = 4PI radian The angular speed of the Ferris wheel is 4PI radians . Multiply by the radius. The linear speed is 100PI feet per minute.

A rotating merry go round has a radius of 30 feet. If it completes one revolution in 20 seconds, find the velocity of the outer edge.
Circumference = 2*pi*radius or diameter*pi
The relationship between revolutions per minute (RPM) and relative centrifugal force (xg) is: g = (1.118 × 10-5) R S2 where g is the relative centrifugal force, R is the radius of the rotor in centimeters, and S is the speed of the centrifuge in revolutions per minute. You can use this for any centrifuge, just measure the radius of the rotor from the center to outer edge.

One formula is: centripetal force = speed2 / radius. Solve it for speed, then convert that to revolutions per second.One formula is: centripetal force = speed2 / radius.

It is 4.1 m/s2 approx.
Assuming rmp means revolutions per minutes, 2*r*pi*rpm (inches/minute).
In each revolution, the wheel would advance 2 x pi x radius. Multiply this by the number of revolutions.
Distance is number of revolutions times circumference. So divide the distance by the revolutions to get the circumference. Then divide the circumference by pi to get the diameter, and divide that by 2 to get the radius.
A hockey puck of mass m = 0.25 kg is tied to a string and is rotating horizontally in a circle of radius R = 1.0 m on top of a frictionless table.
