(4) Angular Velocity II Goal: Practice changing angular velocity. Two ladybugs, one red and one blue but otherwise identical, are sitting on a disk ofradius Rthat is spinning with angular velocity ao. The red sitting at the edge while the blue ladybug is 1/3 of the way from the edge in toward the center. the red ladybug- the blue lady bug- Hint: Do the two ladybugs have the tangential speed? i) Hint: Can you write the centripetal acceleration in terms of only one quantity that varies? ii) Hint: What is the centripetal acceleration (in terms of R) of the red ladybug the blue lady bugExplanation / Answer
angular acceleration of the both the bugs will be zero since it is moving with constant angular velocity
both lady bugs will have different tangential speeds
centrepeta accelerations
Red lady bug = w^2 (R)
blue ladybug = w^2 (2R/3)
Friction keeps up the lady bug to move in circle
Red lady bug will have larger net force
