Homework Help Overview

The problem involves a ball being released from a height above a spinning circular platform with a hole. The scenario includes parameters such as the height of the ball, the diameter of the platform, the rotation period of the platform, and the falling speed of the ball.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • Participants discuss the timing of the ball's release in relation to the platform's rotation. Some mention calculating the time it takes for the ball to fall and how far the platform will rotate during that time.

Discussion Status

There is an ongoing exploration of the problem with participants attempting to clarify their understanding of the timing and mechanics involved. Some guidance has been offered regarding the calculations needed, but no consensus has been reached on a specific approach.

Contextual Notes

Participants note the importance of making an initial attempt at the problem before seeking extensive help, which reflects the forum's homework policy.

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.
