As the Garousel turns, the iders move in a large circle with the chains tited out from the vertical. In one such carousel, the riders move in a 18-m-radius dircde and take 8.5 s to complete one revolution What is the angle of the chains, as measured from the vertical?

Explanation / Answer

Let angle be theta.

tan theta = [mv^2/r]/mg

= v^2/rg = [2pi*18/8.5]^2/[18*9.8] = 1.0036

theta = arctan 1.0036

= 45.1 degree Answer
