A carnival merry-go-round rotates about a vertical axis at a constant

1.	A carnival merry-go-round rotates about a vertical axis at a constant rate. A man standing on the edge has a constant speed of 3 m/s and a centripetal acceleration →a of magnitude 2 m/s2. Position vector →r locates him relative to the rotation axis.What is the magnitude of →r ? What is the direction of →r when →a is directed due east?
Answer» A carnival merry-go-round rotates about a vertical axis at a constant rate. A man standing on the edge has a constant speed of 3 m/s and a centripetal acceleration $\to a$ of magnitude 2 m/s². Position vector $\to r$ locates him relative to the rotation axis. What is the magnitude of $\to r$ ? What is the direction of $\to r$ when $\to a$ is directed due east?
