Question

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 3.43 m/s and a centripetal acceleration of magnitude 2.32 m/s2. Position vector locates him relative to the rotation axis. (a) What is the magnitude of___________.

Answer 1

r = 5.07 m

Step-by-step explanation:

given,

velocity of the man , v = 3.43 m/s

centripetal acceleration, a = 2.32 m/s²

magnitude of position of = ?

using centripetal acceleration formula

`a_c =(v^2)/(r)`

`2.32 =(3.43^2)/(r)`

`r =(3.43^2)/(2.32)`

r = 5.07 m

The magnitude of the position vector relative to rotational axis is equal to 5.07 m.
