Question

You sit at the edge of a merry-go-round of radius 1.5 m. Your friends spin the ride faster and faster. When the period of rotation is 2.5 seconds, you slide off on a tangent. Determine the static coefficient of friction between you and the ride.

Answer 1

first, calculate the force at 1.5m
force=mass*v^2/r=mass*(2PIr/period)^2/r
set that equal to friction force
mass*mu*g=mass*(2PIr/period)^2 /r
solve for mu

Answer 2

Okay, thank you! That makes much more sense :)
