(c) What is the ratio of Jacks centripetal acceleration to Jills centripetal acceleration?-(a) both have same angular vel. ..(b) Vja/Vji = Rω/2.1Rω = 1/2.......

Jack is a distance R from the center of the merry-go-round and Jill is a distance 2.1 R from the center.
(a) What is the ratio of Jack angular speed to Jill angular speed?

(b) What is the ratio of Jack's linear speed to Jill's linear speed?

(c) What is the ratio of Jack's centripetal acceleration to Jill's centripetal acceleration?

(a) both have same angular vel. .. ratio = 1

(b) Vja/Vji = Rω/2.1Rω = 1/2.1 = 0.476

(c)Aja/Aji = Rω²/2.1Rω² = 1/2.1 =0.476
