Katie and Emily are riding on a circular merry-go-round that has a radius of 5 m. Katie is on a horse that is 2.5 m from the center of merry-go-round and Emily is on a tiger that is 4.5 m from the center of the merry-go-round. What is Katie’s tangential velocity if her angular velocity is 0.5 rad/s? What is Emily’s tangential velocity if Katie's angular velocity is 0.5 rad/s?
