Mary and her younger brother Alex decide to ride the carousel at the State Fair, Mary's and Alex's angular speed M and tangential speed vM is mathematically given as
Mary's and Alex's angular speed=1.43
Tangential speed mary=3.22 m/s
Tangential speed alex =2.260m/s
<h3>What is Mary's and Alex's angular
speed M and tangential speed vM?</h3>
Generally, the equation for angular speed is mathematically given as
![w=2\pi /T\\\\Therefore\\\\w=2\pi/3.9](https://tex.z-dn.net/?f=w%3D2%5Cpi%20%2FT%5C%5C%5C%5CTherefore%5C%5C%5C%5Cw%3D2%5Cpi%2F3.9)
w = 1.61 rev/see 3.9
Centripetal acc mary = v^2/r
Centripetal acc mary = w^2r
Centripetal acc mary = w^2x 2m
Centripetal acc. of Alex = w²x L.u
Therefore
![\frac{(ac) mary }{(ac) plex}= 1.43](https://tex.z-dn.net/?f=%5Cfrac%7B%28ac%29%20mary%20%7D%7B%28ac%29%20plex%7D%3D%201.43)
Hence
tang. speed V=Wr
tang. speed of mary = 1.61x2 = 3.22 m/s
tang. speed of Alex: 1.61X1·4 =2.260m/s
