Release Ball to Fall Through Hole on Circular Platform

  • Thread starter dralion87
  • Start date
The ball should be released at a time that is equal to half of the time taken for it to fall, as the disk will have rotated by that time and the hole will be directly under the ball. In summary, the ball should be released after 0.65 seconds in order to go through the hole on the edge of the spinning circular platform.

A Ball Is Held Above A Spinning Circular Platform. The Ball Is 1.3m Above The Circular Platform That Has A Diameter Of .67m And Makes One Complete Revolution In 2.5 Seconds. If The Platfom Has A Hole On The Edge Where The Fall Can Get Through And The Ball Falls At 1.8 M/s...when Should The Ball Be Release In Order To Go Through The Hole?

This belongs on the homework questions section, and you should make an attempt at the solution before asking for too much help. (Hint, think about the time taken for the ball to fall, and how much the disk will spin in that time).

i have made a try i even made a drawing but its still hard...

Well, calculate t, the time taken for the ball to fall. Then work out how far the disk will spin in that time.

FAQ: Release Ball to Fall Through Hole on Circular Platform

1. How does the circular platform work?

The circular platform is designed with a hole in the center and a sloped surface around the hole. When the ball is released, it will roll along the sloped surface and eventually fall through the hole due to gravity.

2. What determines the speed at which the ball falls through the hole?

The speed at which the ball falls through the hole is determined by the mass of the ball and the height from which it is released. The higher the height and the heavier the ball, the faster it will fall through the hole.

3. Can the circular platform be used for any type of ball?

Yes, the circular platform can be used for any type of ball as long as it fits through the hole and is not too heavy for the platform to support.

4. How can the circular platform be used for scientific experiments?

The circular platform can be used to study the effects of gravity on falling objects and to demonstrate the principles of potential energy and kinetic energy. It can also be used to investigate the relationship between the height and speed of a falling object.

5. Are there any safety precautions to consider when using the circular platform?

Yes, it is important to make sure the platform is stable and secure before releasing the ball. It is also recommended to use a lightweight ball and to stand back while the ball is falling to avoid any accidents.
