How Fast Can a Carousel Spin Safely for Toddlers?

Click For Summary
SUMMARY

The maximum safe turning speed for a carousel designed for toddlers under 5 years old is determined using the formula v = √(2gs), resulting in a linear velocity of 4.429 m/s. This calculation considers the safe fall distance of 1 meter, which correlates with the acceleration due to gravity. However, to accurately assess the angular speed, the radius of the carousel is essential, as the term "turning speed" likely refers to angular velocity rather than linear velocity. The discussion highlights the importance of understanding both centripetal acceleration and the potential risks of falling.

PREREQUISITES
  • Understanding of basic physics concepts, particularly centripetal acceleration.
  • Familiarity with gravitational acceleration (g = 9.81 m/s²).
  • Knowledge of kinematic equations, specifically the formula v = √(2gs).
  • Basic understanding of angular velocity and its relationship to linear velocity.
NEXT STEPS
  • Research how to calculate angular velocity from linear velocity using the radius of rotation.
  • Explore the effects of centripetal acceleration on children’s safety in playground equipment.
  • Study the physics of rotational motion and its applications in amusement park rides.
  • Investigate safety standards and regulations for children's amusement devices.
USEFUL FOR

Parents, playground designers, safety engineers, and educators involved in child safety and amusement ride design will benefit from this discussion.

Homework Statement


If a designer finds through research of accident reports at a hospital that children
under 5 can usually survive a fall of 1 m without serious injury, what is the
maximum safe turning speed for a carousel to be used by children of this age?

Hi Alcape! Welcome to PF! :smile:

I'm as confused as you are :redface:

most of the question seems to be missing.

The carousel can be dangerous either because the centripetal acceleration is too much for the brain, or because the child might fall off and hit something.

But, for both, you need to know the radius (and you don't). :confused:
 
Thanks For that tiny-tim I thought their may have been a formula I didn't know of. I appreciate your prompt reply. Thanks again.
 
Thanks for replying I now have an answer If you use the formula v = √(2gs)
where v is the velocity g is the acceleration due to gravity and s is the distance fallen then it comes out to be 4.429m/s...

Yes, that's a possible answer …

but I suspect when the question says "turning speed", it means angular speed (for which you'd need to know the radius). :redface:

(and if that is the right answer, why is the question so complicated … why is it about a carousel? :confused:)
 
I don't know why it's so complicated I didn't make it
