Merry go round-girl letting go of bag

  • Thread starter armor_boy
  • Start date
In summary, the conversation discusses the motion of a bag on a merry-go-round when released by a person sitting at a distance R from the origin and spinning at an angular velocity omega. The conversation also mentions the use of inertial (cartesian) and carousel (polar) frames to describe the motion. The person is seeking guidance on how to present the motion mathematically for an upper level mechanics course. The conversation ends with a suggestion to start by describing the two motions in ordinary English.

Homework Statement


Imagine watching friend on merry go round sitting distance R from origin and spinning at ang. velocity omega. She let's go of bag she is holding. What is trajectory of bag in inertial (cartesian) and carousel (polar) frame?


Homework Equations





The Attempt at a Solution


I understand the motion in inertail and carousel frame as far as the way it looks but presenting it mathematically is uncertain. Can you give me some direction as to where can I start. It is for graduate course so it is upper level mechanics

FAQ: Merry go round-girl letting go of bag

What is the "Merry go round-girl letting go of bag" phenomenon?

The "Merry go round-girl letting go of bag" phenomenon is a viral video that shows a young girl on a merry-go-round letting go of her bag while spinning at a high speed. The video gained popularity due to the girl's seemingly calm reaction and the bag's movement mimicking the rotation of the merry-go-round.

Why does the girl let go of her bag on the merry-go-round?

The girl most likely let go of her bag due to centrifugal force. As the merry-go-round spins, objects on it experience an outward force, causing them to move away from the center. In this case, the girl's bag was pulled towards the outer edge of the merry-go-round, eventually slipping out of her grasp.

Is the "Merry go round-girl letting go of bag" video real or fake?

The video appears to be real, as it was filmed in a public park and the girl's reaction seems genuine. However, some people have speculated that the video may have been staged for entertainment purposes. Without further evidence, it is impossible to determine the authenticity of the video.

What can we learn from the "Merry go round-girl letting go of bag" phenomenon?

This phenomenon is a great example of how physics can be applied to everyday experiences. It demonstrates the concept of centrifugal force and the importance of understanding the laws of motion. Additionally, it showcases how even small actions can have unexpected consequences.

Can the "Merry go round-girl letting go of bag" phenomenon be dangerous?

While the video itself may seem harmless, it is important to remember that amusement rides, such as merry-go-rounds, can pose potential safety risks. It is always important to follow safety guidelines and precautions when using amusement rides, and to never imitate risky behaviors seen on the internet.
