Question

You are sitting on a merry-go-round that is accelerating with a constant angular acceleration. As the merry-go-round goes faster, which of the following is not increasing?

A)Angular Velocity

B)Tangential Acceleration

C)Centripetal Acceleration

D) Tangential Velocity

E) All are increasing

Answer 1

In the the problem it is given that merry-go-round is accelerating with constant angular acceleration : constant If the merry-go-round has angular acceleration that means it's angular velocity (W) is increasing: Now tangential velocity, V = pw; an increases increases V also Νσω centripetal acceleration is given by 1 ac V2 r As vis increasing ac also increases. by , Tangential acceleration is given ; where angular acceleration a a ar AS a and r are constant SO a is also contant. :. Tangential acceleration is not increasing
